Window opening limiter (comb) for plastic, wooden, aluminum windows. Installation and Retailing.

The window opening limiter (comb) is now almost a mandatory attribute of it.
The limiters described below can be installed on plastic and wooden windows, sometimes on aluminum ones.

Types of window opening limiters.

The window opening limiters on the market can be classified as follows:
According to the material of manufacture- plastic and metal.
By appearance- Euro combs and USSR combs.
By appointment- for normal ventilation and for safe ventilation (such restrictors are effective protection for children).
On this page of the site we will talk about metal window opening limiters, if you are also interested in plastic limiters, go to the comb for plastic windows page.

Window opening limiter for normal ventilation.

Euro-combs metal (imported production).

Such a window opening limiter has a very useful feature - displacement / rotation by a small angle to the right / left. This allows you to mount the limiter at some distance from the sash, which can be useful later when adjusting the sash. The pin has a rubber cambric, so the opening limiter is put on tightly, without play, which means there will be no metal rattle during wind gusts. The pin is fastened with self-tapping screws into the overlap of the sash, and not under the handle. The pin fastening is secure. But since for fastening the pin it is necessary to "spoil" the sash with two holes, we will call such fastening vandal.

Let's repeat. The pin is fastened with screws into the overlap of the sash, and not under the handle, therefore, such a limiter should not be installed on wooden windows, since the tree may not withstand strong wind loads and will crack in the direction of the fibers (the overlap only seems strong, it has a groove under the seal).

Euro-combs metal and plastic are not interchangeable:
1. The comb attachment area (the one where there are holes for self-tapping screws) is wider than that of the plastic one, 15mm instead of 12mm, so it may not fit between the wings.
2. Holes for fastening screws, this opening limiter and plastic do not match.

Ideal for plastic windows in rooms with a large number of honest users, otherwise, after a while, the limiter may not be in place.

The cost of a comb without installation (from 1 pc.) - 450 rubles
The cost of the comb with installation - 550 rubles

Euro-combs metal (Russian production).

The material for the manufacture of the window opening limiter is a metal alloy containing zinc, aluminum and copper. Cast zinc alloys are most widely used in the automotive industry for casting carburettor bodies, pumps, speedometer frames, radiator grilles, hydraulic brake parts, and various decorative parts.

The appearance is the same as the plastic euro combs, but one position more (5 fixations, not 4). Color - the comb itself and the base pin are white, brown. They do not have the ability to shift / rotate right / left. The limiter is put on the pin without tight fixation, but it can be provided by wrapping tape.

Flaws: not only does it not have the ability to shift to the right / left, but it also does not bend, so you can put it on a pin (in the case of a rotary, not a folding opening) with a significant effort, which, most likely, will lead to loosening of the pin (this is on plastic windows). And on wooden windows, over time, cracks may also appear at the place of attachment of the comb itself. To avoid this, it is necessary not to wrap the self-tapping screws of the opening limiter to the end and it will hang out by itself. But this can hardly be considered a convenient use, because. with gusts of wind, rattling is not ruled out.

Where should these opening restrictors be used:
1. The use of this comb is justified on large windows, which are used primarily in the tilt position in rooms with drafts to prevent slamming.
2. Suitable for any window to which they fit in geometry (subject to our installation).

The cost of a comb without installation (white) (from 1 pc.) - 200 rubles.
The cost of a comb without installation (box) (from 1 pc.) - 230 rubles.
The cost with the installation (white) (without rattling and maintaining the shift to the right / left) - 350 rubles
The cost with the installation (core) (without rattling and maintaining the shift to the right / left) - 380 rubles
The minimum order value (with installation) is 2000 rubles.

USSR-combs. Metal (Russian production).

The window opening limiter is made of powder-coated steel. The limiter has five fixations. The width of the fixation slot is 5.7mm. Color - white, pin base - white. They have the ability to turn/shift to the right/left. The set can be with or without a base pin (in this case, any self-tapping screw can serve as a pin).

Flaws:
1. The first slot is significantly removed (it is approximately at the level of the second slot of the plastic Euro-comb), so micro-ventilation is impossible. For the tilt position, only the first two slots are available, with the second fixing the maximum tilt. Moreover, since the amount of tilt depends on the height and width of the sash, it may happen that only one first slot is available for fixing the sash in the tilted position.
2. The window opening limiter is elongated, so if the window sill is narrow and the handle is at head level, you can get injured when fixing a small opening.

Where should these opening restrictors be used:
On windows that mainly open in a turn mode and when a maximum opening angle is required.

The cost of a comb without installation without a pin (white) (from 1 pc.) - 80 rubles.
The cost of a comb without installation with a pin (white) (from 1 pc.) - 160 rubles.
The cost of a comb with installation (with a pin) is 350 rubles.
The minimum order value (with installation) is 2000 rubles.

Disadvantages of window opening limiters.

The disadvantages of window opening limiters include:
1. The window remains fixed but not closed. If the room is located on the lower floors, then it becomes available to the attacker.
2. For young children, this is not a window lock, but rather something interesting that needs to be touched and overcome.
3. Even if the sash is in the hinged position, the air flow is distributed not only vertically, but also horizontally, and being near the window is not always pleasant and useful.
4. The window is open, which means that all its soundproofing properties disappear.
5. Even with the smallest of possible openings, the sash opens / leans back on three sides of the perimeter and the total area of ​​​​the gap turns out to be quite large, therefore, at low temperatures, the room quickly cools down. In winter, at night, you can hardly use a comb, it will be very cold.

Supply ventilation valves.

However, the need for access to fresh air into the room remains even at low temperatures. Window ventilation valves help provide this access.
About supply ventilation is described in detail on the window ventilation page, about the types of valves on the page supply ventilation valves.
If with the help of window valves you are going to solve problems: fogging of windows, stuffiness of the room, "weeping" windows, mold formation on window slopes, then an average performance valve is enough.
The problem of a clear lack of fresh air, i.e. "to breathe" with the windows closed can be solved by installing high capacity valves or a few medium capacity valves.

Window opening limiter for safe ventilation.

Aluminum window opening limiter (Russian production).

Until recently, there was only one type of window opening limiter for safe ventilation - BABY SAFATY, but in 2011 a Russian limiter appeared, it leaves the window safe in the turn and tilt position.

We do not sell or install.

Opening limiter metal, for aluminum windows.

This opening limiter is installed on "warm" aluminum windows and on hinged windows made of PROVEDAL ("cold") aluminum profiles and its analogues.
In terms of the number and "size" of possible fixations, it is similar to the USSR-comb.
Limiter - steel, for 5 fixations, color-white.
Pin - steel, white, installed under the handle.

The following is important to be able to install the comb (please check):
- the appearance of the handle (shown in the photo),
- dimensions of the base of the handle, they are: width - 27mm, height - 135mm,
- the principle of operation of the handle - when the handle is turned, the "pushers" converge and diverge (look from the other side of the open sash),
- free space (on the frame) for installing the limiter - this is the distance from the edge of the sash (opposite the handle) to the nearest something (wall, slope, neighboring sash, bay window connection, etc.). There must be at least 18mm of free space, since the width of the base of the limiters is 17mm.

If the appearance or dimensions of the base of the handle (on your windows) are different, and, in your opinion, it is impossible to install the limiter, send a photo to the mail, maybe something will come up.

The opening limiter is sold only with installation, the cost is 600 rubles, the minimum order amount is 1600 rubles.

Window sash opening limiter (aka "comb", aka "crocodile") is a window ventilator. It consists of two parts - a comb (a small bar with recesses) and a retainer. The latch is mounted on the movable sash of the window, the comb itself is fixed on the frame. Please note that the window comb simply fixes but does not lock the window.

Combs are used for controlled ventilation of the room on PVC or wooden windows. They provide the possibility of fixing the sash in 2 planes: vertical and horizontal.

Plastic comb (installation under the handle)

There are options available:

Plastic comb with 4 positions. Length - 10 cm.

Plastic comb for 5 positions. Length - 12.5 cm.

The window opening limiter comes with painted fasteners installed under the handle of a plastic window.

Materials from which the comb for plastic windows is made:
- metal part under the handle made of painted galvanized metal,
- the case - from high-strength ABS plastic.

The principle of operation of the comb

The comb window limiter is the most economical option for limiting the opening of the sash.

The principle of operation is very simple: depending on how much fresh air you want to provide, the size of the gap between the sash and the frame is selected, the slotted bar is thrown over the protruding pin of the latch.

The window comb can be installed on any plastic windows from any profile. And not just on the windows! The comb can also be placed on the balcony door.

Why do you need a window limiter "comb"

The window sash limiter in the form of a comb (crocodile) is needed to limit the opening of the window sash. A window equipped with a comb can be easily fixed in the open and ajar position. Fresh air will enter the room through the resulting gap between the frame and the window sash. In this case, the comb will provide a rigid fixation of the sash in the position you need. This avoids strong drafts when airing the room, which is especially important in winter.

In addition, if you have pets like a cat that love to sit on the windowsills and look out into the street, then you simply need such a limiter. Through a narrow gap left by the limiter, your beloved animal will not be able to climb onto the ledge and leave you.

Comb sash opening limiters allow you to leave the fixed window sash unattended, without fear that the window will open with a gust of wind.

Advantages of a comb

• low price
• easy installation - no special skills required for installation
• installation "under the handle" allows you to put the "comb" limiter on both plastic and wooden windows
• the ability to choose the appropriate color - white or brown - depending on the color of your windows.

How to install a comb

To install the comb on the window, you must have at hand: at least one comb, 2 screws, a screwdriver.

If you forgot the screwdriver in the garage, you can use a regular screwdriver, as shown in our series of photos.

To install the comb on the window, you must first remove the handle from the window sash. To do this, turn the cover and unscrew the handle screws. One screw on the top and one screw on the bottom.

Then install the counter part of the comb with the rod on the handle.

Put the handle back in place.

Attach the comb itself to the box opposite the counterpart, located on the window sash under the handle, and mark the place of the self-tapping screw with an orange felt-tip pen.

Secure the comb with two self-tapping screws and a screwdriver (screwdriver). Since the combs can be installed on plastic, wooden or aluminum windows, self-tapping screws must be purchased independently, based on the window material, they are not included with the combs.

As you can see, installing a comb on a plastic window is an easy process and takes very little time.

By changing outdated wooden windows to modern metal-plastic ones, customers often try to save money. Cost minimization primarily concerns fittings, and many customers of window installation companies find that a window opening limiter is something they can do without. In fact, this small device costs mere pennies, and the benefits of it are not at all as small as it might seem at first glance.

We complete our windows

By the name of this item alone, it is clear that it must fix the sash either in a given standard position (open / closed / micro-ventilation), or expand this rather narrow list of window possibilities. Some companies offer their customers to purchase a plastic window opening limiter even before they are installed, which is the most reasonable option, because then the latch fits perfectly to the profile. However, subsequent installation is quite possible, in addition, you can use not only the standard limiter model offered by the profile manufacturer, but choose another, more suitable option.

There are several types of window opening limiters, each of them has its own advantages and disadvantages. You can learn about each of the types, as well as the pros and cons of specific models from this article.

Briefly about the main

So, the limiters presented on the domestic market are of five main types:

1. Several modifications of the combs - there are external and internal ones, they are made of PVC, they are easy to install, in addition, this option is the most budgetary.
2. An internal window opening limiter that prevents the sash from swinging open and fixes it in a predetermined position. Made of metal, has a simple but reliable design, durable.
3. Window opening limiter with a cable - looks quite aesthetically pleasing, is a structure made of a metal core, 5-10 mm in diameter, in a polymer braid, which is easy to wipe from dirt. It is strong, safe, has a high level of opening-closing rate, because it is practically not subjected to mechanical stress.
4. The lock limiter for opening plastic windows, the main function of which is the ability to close the sash with a key.
5. Swing opening limiter, with the ability to put the window in the "window" mode.

Different models of these clamps can differ significantly in appearance, however, they have a similar principle of operation. An important nuance that needs to be reported to the master when placing an order is the type of the window itself, or rather, what type of mechanism the sash has (hinged or hinged-hinged).

Comb limiter - bestseller

Of course, the most popular model of a device that fixes metal-plastic windows is a comb. There are several models of this type of device. More often than others, it is customary to use an external window opening limiter. The comb is then located from the visible part of the sash. It looks unpretentious - this is a plate with grooves, which is attached to the immovable part of the profile, and the second part of the device is screwed to the sash - a hook fitted to the size, for which the bar clings. Due to the fact that it has 3-4 connectors, this allows you to fix the window in several positions. A comb is also a good option to install a stopper for wooden windows, because it does not need to be integrated into the mechanism of the window system.

There are also more complex mechanisms - these are internal limiters, which are also made of plastic (white or brown, less often - other colors). There, the comb is part of a sliding mechanism that is installed between the sash and the profile.

under lock and key

Some modifications of stoppers are systems with locks that are locked using special keys. Among them is a window opening limiter, which is located directly in the handle. In the closed position, it disables the possibility of opening the window wide open, but the ventilation and micro-slit function remains.

This model assumes, first of all, security, because it is an additional means of protecting the premises from intruders. It is also a good way to protect children and pets from the danger of falling out of the window.

Complex structures

From a technological point of view, the most time-consuming in installation and principle of operation are internal limiters. Models from this series provide braking of the sash and do not allow it to open wider than at an angle of 90º. This device is very small, it is equipped with three grooves that help adjust the angle of the window opening.

The advantage of using this method of fixation is its invisibility, however, it is better to install it at the time of assembling the window itself, so that it would be more convenient for the master to adjust all the moving parts of the structure (hinges, handles, swinging systems).

Safety is above all

The most common reason for installing a restraint is to ensure the safety of children. Curious by nature, they often like to spend time at the windows, watching what is happening outside the house. Unfortunately, cases when babies fell out of windows, leaning on a mosquito net, happen more and more often.

By installing a similar latch on the window, parents can prevent the tragedy without depriving the kids of the pleasure of looking out the window and without closing it tightly. Ventilation of the room is also often complicated, because it is not always necessary to open the window wide open. Depending on the time of the year, it is necessary to adjust the width of the gap sufficient to ventilate the room. Opening limiters will help you find the best option and ensure comfort in the house.

Last but not least, the reason for installing a limiter is to protect the slopes and walls from damage resulting from excessive opening of the window. This can be done by the owner of the premises himself through negligence, or it can also be the result of a draft. In any case, it is better to initially install a limiter, the cost of which does not exceed several hundred rubles, than to subsequently repair it.

Master or hand-made?

The window opening limiter can be installed independently if the latch model is external. Then you need to attach the details of the limiter to the sash profile and frame. Before fixing the elements, you need to outline the places where they will be placed. The clamps are fixed with self-tapping screws using a screwdriver or screwdriver.

It is better to entrust the installation of devices with more complex modifications to specialists. Even minimal intervention in the window system can lead to a violation of the mechanism, and then the window will not fit snugly against the frame due to the displacement of the elements. As a result, the window will lose its soundproofing and energy-saving abilities.

So that the door does not slam, does not open / close spontaneously, so that it can be fixed at any angle, there is a door opening limiter. There are many types of limiters. They differ from each other constructively, in location, in design. You can choose an element that will be combined with the rest of the door hardware.

Varieties

1. The simplest floor door stop is a wedge with a non-slip base. Designed to limit the door so that it does not open wider than necessary.

2. Another floor stopper is put on the door at the bottom. It is equipped with non-slip feet that rest on the floor. When opened, the door is released from the groove and set in motion.

3. Magnetic door stop. It consists of a latch with a magnet located on the floor, and a mating plate on the canvas. When opening, the parts are connected and hold the door in a certain position.

4. Wall-mounted door stop (opening latch) - an element that is installed on screws in the place of the wall where the opening of the door should stop. When opened, the door rests against it and does not hit the wall. Such a door opening limiter can be conventional and magnetic.

5. A latch that is attached to the casing at the top of the box. When turning down at a right angle, an obstacle is installed to slam the door. In order not to damage the canvas, wall stops are equipped with rubber gaskets or made of soft materials.

6. A C-shaped plastic latch is put on the end of the leaf and thereby prevents the door from slamming.

7. Opening angle limiter. A metal device that is installed on the door. The brake shoe is equipped with a pedal. The pedal is pressed to fix the canvas. To set it in motion, the block is raised by means of a lever.

8. Latches. Inside the apartments are used most often in bathrooms and kitchens. Usually this is a tongue, which, when fixed, enters the corresponding groove of the striker. There are also magnetic varieties.

Video "Installing the door stop":

9. Front door locks. When installed, the door from the outside cannot be opened with a key. Magnetic latches prevent the door from slamming shut when you enter the stairwell.

The choice of a door opening limiter is determined by the intended purpose, ease of use, design and features of the room (for example, if the apartment has a warm floor or expensive flooring, wall mounts are preferred).

Plastic double-glazed windows operate in two modes: slotted micro-ventilation and full opening of the sash. However, such provisions are often not enough. A practical and affordable solution to the problem is a window opening limiter. The device holds the sash at a given level, preventing it from slamming or swinging open in the event of a draft. Let's figure out what types of window fixers exist and how they work. Let us designate the selection rules and the technology for mounting the limiter.

The window limiter controls the air flow into the room and keeps the sash in the selected position. The bar sets a fixed opening gap in the range - 1-10 cm.

leaf lock

Window sash limiter tasks:

1. Air supply adjustment. The desired intensity of ventilation is set in the room - the air flow circulates in a certain volume through a fixed slot.
2. Safety. The bar blocks the position of the window - it will not allow it to open wider than a given level. This is very important for families with small children and pets.
3. Draft prevention. The mechanism keeps the sash from sudden opening. Due to this, the likelihood of unforeseen drafts is reduced. In addition, there is no risk that nearby objects, flowerpots and expensive double-glazed windows will suffer from a sudden opening of the window.

For your information. Poor ventilation of the room is one of the main reasons, and in the rooms.

Components of the limiter

A typical blocker is called a "comb" or "crocodile" because of the appearance of the device. The latch is distinguished by its uncomplicated design and operation scheme.

The simplest model of a window stop consists of two parts:

1. Comb. Extended bar with slots and swivel for raising/lowering the mechanism. The number of "notches" on the plate determines the window opening range. The most popular four-position models.
2. Retainer. The response part is located on the movable sash. A small metal pin holds the comb in place.

Window stop device

The use of the limiter consists in choosing the level of opening of the window and placing the pin between different positions of the comb.

Pros and cons of using a blocker

The main advantages of limiters for plastic windows are the ease of use and the safety of operation of the sashes. Additional benefits include:

• affordable cost;
• the ability to use on previously installed windows;
• ease of installation - all work can be done by hand without the involvement of specialists, the use of expensive equipment;
• uncomplicated care of the mechanism and the possibility of its independent replacement in case of breakage.

Window frame blocker

However, this method of fixing the window sash also has disadvantages:

• non-observance of the installation technology is fraught with damage to the frame and deterioration of the tightness parameters;
• fragility of the structure - active, careless operation can disable the latch or lead to the breakdown of the bar;
• in the cold season, the use of a limiter is not relevant - the air inside the room cools quickly. One way to ensure ventilation in winter is to install.

A simple comb is not enough to fully protect children. To ensure complete security, it is necessary to install lock models.

Types of window sash retainers

Window stops for PVC windows differ in the material of manufacture, installation location and mechanism of action. These parameters determine the strength of the blocker, its durability and reliability in terms of safety.

According to the material of manufacture

Three types of models are used for installation on PVC windows:

• plastic;
• metal;
• combined.

Plastic. Affordable device, perfectly compatible with PVC profiles. Limiters are available in several colors, the standard number of positions is 3-4 positions.

plastic limiter

Cons of PVC blockers: low strength, short service life. It is undesirable to mount such modifications on sashes facing the windy side - strong loads can provoke plastic deformation.

Metal. More durable, and therefore wear-resistant blockers. The most preferred are brass limiters with an anti-corrosion zinc layer. The color range of metal clips is limited: golden, silver, grayish and copper shades. Minus - high cost.

metal limiter

Metal-plastic. Combined devices include: plastic comb and metal retainer. As a rule, the strap is white. Interesting multi-colored options - to order.

Combined blocker type

According to the method of fastening

There are 2 mounting methods:

• installation under the handle;
• installation in the overlap of the sash.

The first option is conventional combs mounted on the fixed part of the frame. The bar rises or falls without taking up extra space and without clinging to the curtains.

Placement of the limiter under the handle

The second option involves installation at the end of the sash. The pin is fixed with long self-tapping screws that pass through both jumpers of the overlap of the sash. Such a mount is more reliable.

The limiter for opening the window sash into the overlap is only suitable for plastic structures. Mounting on a wooden frame can cause it to deform along the fibers of the natural material due to the significant forces exerted on the pin.

Blocker at the end of the sash

According to the mechanism of action

Limiters for opening plastic windows according to their design features and principle of operation can be classified into the following groups:

1. External comb. Primitive "crocodile" for flaps. The model fixes the window for ventilation, but at the same time the degree of protection for children is insufficient.
2. Built-in limiter. An analogue of an external comb, in terms of functionality it corresponds to the previous device. Plus - aesthetics, secrecy of placement. Cons: Doesn't provide security.
3. Permanent brake. Blocks spontaneous opening, excessive opening of the sash. A similar mechanism is used on the doors of offices, shops. Disadvantages: high cost, risk of breakage when the window is suddenly opened.
4. Lock handle. Effective protection against children's access to windows. Outwardly, this is an ordinary handle, but shutoff valves are mounted inside. Minus - a limited choice of the position of the sash, the need to save the key.
5. Window stopper with cable. In terms of capabilities, it is similar to a comb, but is able to withstand a tensile force within 550 kg. Mounting on hinged doors is possible anywhere, on tilt-and-turn frames at the top of the structure.

Rope stop for window rotation

How to choose a window comb

Before buying a window stopper, study the characteristics of various modifications. When choosing, experts recommend following these rules:

1. It is better to mount the mechanisms of the included brake on the balcony blocks.
2. For attic double-glazed windows, large windows, it is necessary to select metal clamps of increased strength.
3. With active use, frequent opening / closing of the sashes, it is advisable to choose a window stopper with a cable. An alternative option is a blocker with a locking mechanism.
4. If drafts often “walk” in the apartment or windows are located on opposite sides, give up plastic products.
5. To protect children as much as possible, it is necessary to mount special restrictors for safe ventilation or.

How to install a window stopper

The technology for mounting a window retainer according to the type of comb can be divided into three stages. The first is preparatory activities. The second and third are the installation of a latch and a strip with grooves, respectively. Let's analyze each of them.

Instrument preparation

Prepare your tools ahead of time. Having everything you need nearby will help you stay focused on your work.

Required tools and materials:

• pin limiter;
• screwdriver or Phillips screwdriver for fixing elements;
• self-tapping screws up to 10-12 mm long - larger fasteners can damage the window profile;
• construction or household knife - necessary for prying the plug;
• marking pencil - it is better not to use a marker on white plastic so that there are no traces left;
• drill and drills.

At hand, you must have a tape measure and instructions supplied with the limiter for PVC windows.

Required Tools

Retainer installation

The first task is to install the pin on the opening sash of the window.

Sequencing:

1. Pry off the plug on the handle and rotate it 90 ° - access to the fasteners will open.
2. Fix the window in the open mode and remember the position of the handle - perpendicular to the vertical of the sash.
3. Unscrew the top, bottom bolt and remove the handle.
4. Place the comb bracket so that the board is under the window handle. The pin should look towards the reciprocal sash.
5. As a rule, the holes of the bracket coincide with the holes for the location of the screws.
6. Attach the bar with the pin, reinstall the handle and tighten the bolts.
7. Return the handle cap to its original position.

Installing the window stopper

Bracket mount

This is the most important step in installing a window stopper. Here it is important not to make a mistake with the marking and preparation of holes for mounting the comb - it will not be easy to fix the defect. Illiterate actions can lead to depressurization of the double-glazed window.

Work performance technology:

1. Close the sash with a latch and mark the level of the bracket. The pin should be located opposite the comb, but not interfere with the free opening / closing of the window.
2. Mark the planned location with a pencil.
3. While holding the toothed bar in the designated area, try to fix the window, check the operability of the sash.
4. If the elements are well joined, the limiter does not prevent the use of a double-glazed window, then you can finally screw the bracket to the frame with self-tapping screws.

Checking the operation of the sash opening blocker

The guide is undesirable to "sit" on the glue. Constant loads will quickly spoil the strength of the hitch and the bar will fall off.

The whole process is clearly demonstrated in a step-by-step video instruction:

Features of replacing the old element

Before you install a new limiter on plastic windows, you should consider a few important points:

1. We need to find an analogue of the old comb. When buying, pay attention to the basic dimensions: the diameter of the pin and the distance between the mounting holes.
2. Even if only one element fails, the entire system must be replaced. Fasteners of different models may have dimensions that will not fit the new plank grooves.
3. To change the brackets, you need to unscrew two self-tapping screws.

Replacing the sash opening limiter

When rearranging the bar, a number of rules are followed:

• plastic residues on self-tapping screws must be removed - if this is not done, then there is a risk of stripping the thread during tightening;
• it is desirable to get into the old, worked out thread - first scroll the self-tapping screw counterclockwise, and as soon as the fasteners “fall off”, change the force vector.

If the holes of the new comb do not correspond to the old ones by 1.5-3 mm, they can be bored with a needle file, and the bar itself can be fixed with screws with wide heads and press washers.

Making a limiter with your own hands

For the windows of a country house, you can build a home-made device for regulating ventilation. You will need simple materials:

• cut wire with a diameter of 2-3 mm;
• 2 small nails - will act as a pin;
• 2 large nails - for making staples and then fixing the restrictive device on them.

Making a window blocker

Assembly algorithm:

1. Bend the wire in half, forming a loop in the middle, and small curls along the edges.
2. Make an arch out of long nails. To give them the desired shape, use pliers.
3. Drive staples from long nails into the fixed frame of the sash at a height convenient for adjustment.
4. Thread one end of the wire into the bracket.
5. On the movable sash, fix a small carnation - a tripod.
6. To adjust and fix the position, the wire ring must be put on the lock.

If the invention provides for several turns of wire, then this will expand the number of window opening modes.

A home-made device does not require financial investments, but is noticeably inferior in strength to purchased counterparts.

Limiters do not require special care. Periodically it is necessary to tighten the fasteners, check the reliability and integrity of the comb. If necessary, you can replace the window retainer.

It is undesirable to use the comb in frosty weather, with heavy gusts of wind, heavy rains, it is necessary to close the windows in a timely manner and not load the blocker. This is due to significant pressure on the sash and the latch itself, which will not always be able to withstand it.
