Decor elements

Today plastic windows are almost universally installed. They are durable, functional, provide reliable heat and sound insulation. Increase the comfort of PVC glass pumps, while at the same time making them safe for children and pets, allow window limiters.

Features

The window limiter is a design that allows you to open the window, leaving a small gap and fixing the window sash in a given position. The name "Comb" device received for the external similarity with the comb. It has several grooves. In any one can be placed the rod, which allows the open window in the same position, and households and pets are not approached too close to the window to the window.

The comb is installed on the windows of the rotary type, that is, on those where the sash opens exclusively in the horizontal direction. In fact, the limiter allows you to open the sash like the window. However, nothing interferes with installing a comb on windows with a swivel-folding mechanism. Its use will reduce the clearance formed when opening the sash in the vertical direction.

The design consists of a plank with slots and a locking position of the window sash (rod). The bar is mounted to the frame, the retainer is installed in the window sash. By installing the retainer in a particular groove, it is possible to open the window within 1-10 cm. The opening angle depends on the length of the plank with the grooves and the number of the latter.

The greater the grooves the bar, the more accurate adjustment of the position of the sash can be achieved. Standard is considered a bar with a size of 10-12 cm with 4 grooves.

Manufacturers of limiters usually indicate 2 basic functions of the comb:

carrying premises (especially relevant for windows that do not have additional valves, sash opening exclusively horizontally);
protectionglass package from damage due to a sharp slam of the sash due to draft, strong wind.

Ensuring the safety of children and domestic animals is another advantage of the limiter.

Adjusting the position of the comb, the user has the ability to open the sash wider or already. Due to this, it is possible to achieve an optimal microclimate in the room, prevent condensate formation on a plastic double-glazing, not overcoholing the room.

In this position, you can leave the window at least for the whole day (which is especially relevant in the warm season). Opening a window literally by 5-15 cm and using the limiter, you will provide optimal air circulation indoors. However, it is important to understand that the ridge only fixes the window, but in no case is the locking device. Residents of the first floors should not leave windows with open and fixed limiters, leaving the house.

In addition to explicit advantages, the design has both "minuses", which is better to know about the purchase and installation of the ridge. Installation of the device assumes the presence of additional perforations in the profile, which slightly reduces the thermal insulation properties of the glass package. Sound insulation coefficient is also reduced by 2-3 dB. Finally, the presence of holes leads to a decrease in the strength of the profile, possible disorders of geometry.

If you compare the supply valves with limiters, the latter, of course, lose them in their safety and functionality. The operation of glass windows with valves is more convenient, but such products are more expensive.

Views

Limiting elements may differ in the number of grooves. Standard models have 4 grooves, but there are options with 5 grooves. In addition, there are several types of combs.

Outdoor

It is provided for folding windows (for example, forges). It has a 3-4 groove, fixes the sash during the air ventilation.

Built-in

Unnoticed analogue analogue of an outdoor comb. In its functioning and number of grooves, this option is identical to the above. The difference is the big aesthetics of the window, since the built-in limiter is immeasured.

Permanent brake

Perhaps this name will seem to many unknown, although it was faced with such mechanisms for flaps, perhaps everyone. The constant brake is usually installed on the door of shops, offices. A person is enough to pull the door and open it. No need to close. Thanks to the built-in mechanism, the door smoothly flashes automatically.

A similar system is mounted on the window, without allowing the sash to spontaneously close or overcapped. Such a mechanism cannot be pulled by force, trying to cover up the window, as it can break.

Cable limiter

Structurally, it consists of 2 elements, one of which is fixed on the frame, and the second is on the profile. Between themselves, they are connected by a metal-based cable (sometimes in a plastic braid). There are models where the cable is replaced by a thin chain. Microwing function is implemented due to a small (up to 20 cm) the length of the cable.

Unlike the standard comb, it does not allow to fix the sash, but only holds it, Preventing further swollen window. At the same time, the cable limiter is a stronger comb and can withstand an effort to break up to 550 kg (depends on the model).

To protect against children and unauthorized penetration from outside, the cable limiter is suitable more than a comb. For venting, it is better to choose the last one.

When installing on the rotary flaps, the limiter can be mounted anywhere in the profile and frame, when attached on rotary-folding structures - only at the top.

Handle-castle

This is the most efficient limiter providing protection from the opening of the window by the children. It is a metal handle with shut-off reinforcement. The castle is located on its outer part. Opening is made by the key.

Using the key, you can reliably close the sash or give it a folding position. In its appearance, such structures are indistinguishable from ordinary handles. The inconvenience is the need for key safety. To do this, find a place inaccessible to children. The use of the key also includes the overhead and mortise locks installed on the glass, as well as the lock limiter and blockers for the sliding type windows.

Depending on the material used, several varieties of the comb differ also.

Plastic

This is the most accessible view. It can have several color finishing options, well combined with PVC structures. The basis is the ABS (shockproof) plastic. Standard number of grooves - 3-4.

Of the disadvantages you can select the smallest indicator of strength and, accordingly, a shorter period of operation. It is not recommended to install such products on the windows overlooking the windows, because with heavy loads they can be deformed and burst.

Metal

Metal combs are stronger and more durable, and therefore have a higher cost. It is important to consider that the metal of the product must have anti-corrosion protection. Brass is considered the best material for making the design. To protect it from corrosion, necessarily the presence of a zinc layer. Usually such products have 4-5 teeth. Color range is very wide (copper, golden, silver, gray shades).

Combined

Such a device includes at once 2 material - plastic and metal. As a rule, the latter serves as the basis for the retainer, while the comb is performed from plastic. The number of teeth can vary from 3 to 5. more often produced white products of this type. Sometimes you can find brown combs designed for windows with a profile under wood. Colored options are usually made to order.

Depending on the type of installation, the limiters mounted under the handle of the sash are distinguished, as well as analogues installed in the end of the window sash.

How to choose?

You can buy products in specialized stores, household accessories, as well as specialists engaged in the production and installation of windows. It is better to give preference to structures from durable materials of simple forms. This will increase the durability of the limiter, reduce the risk of decaying its individual elements.

It is important that the limiter corresponds to the features of the glass package and operating conditions.

For example, it is better to install the mechanisms of the included brake. For overall windows, as well as mansard double-glazed windows opened up, only metallic limiters of increased strength should be chosen.

If active operation is assumed to operate the glass and frequent opening / closing, it is better to prefer the mechanism with a lock and key than a conventional comb. Then the device will last longer.

The cost of products varies within 100-500 rubles. It depends on the material of manufacturing, producer, the number of grooves. The most accessible are plastic models, more expensive - metal and combined. Also, usually comb with a large number of grooves have a higher price.

How to install?

The combing installation will take literally 5 minutes. The process does not require professional skills, you can do all the work with your own hands. The following tools and materials will be needed:

directly the window limiter, which includes the comb, retainer and brackets;
self-tapping screws, which are also included in the kit (you can choose them yourself, the main thing is not to take fasteners, the length of which is more than 12 mm, otherwise it will damage the profile);
screwdriver or screwdriver;
knife (construction or ordinary kitchen), with which you need to pick up the plug;
pencil or washes marker for applying;
drill.

Put the limiter can be in several stages.

After preparing all the necessary to work, drill in a few holes in the window using a drill. With this tool, you will receive perforations without damaging the profile plastic. If you neglect this stage and try to immediately screw the screws, avoid cracking the material of the profile will not work.
Turn the plug at right angles. To do this, find a special groove on its surface, picker it with a knife and turn 90 degrees. As soon as the procedure is executed, 2 bolts will be detected under the plug. They must be unscrewed.
Remember, in what position the window handle is, then remove it. Avoid confusion will help giving the handle of the same position that it has when the window is open, that is, the handle must be perpendicular to the window vertical.

Place the limiter bracket in the profile space so that in the future it is under the window handle. Bracket holes should be visible perforations for screws. After that, the handle is installed on the bracket, that is, returns to its former place.
Take the lock, align it with the bracket axis (it must be correctly entering the grooves). By defining the optimal position of the retainer, the corresponding marks on the profile should be made.
In the marked places with a drill with a thin hydraulic, 2 holes are performed. Then you can fix the limiter using the screws. After that, the installation is considered complete.

Slightly otherwise installing the retainer in the end of the sash. This type of installation allows the arrangement of the comb anywhere in the stationary part of the frame. To attach the lock, you should use a long self-sufficiency so that it can break through both the inner lintels of the end part of the sash (it is also called from the outlook). Only in this case, you can count on the reliability of the attachment. As with the use of the previous method, it is important to pre-drill holes for screws, and screw the fasteners in them.

Installing the limiter in the end part of the sash usually performs an alternative option. It is resorted to it if under the handle of the window or opposite it has accessories, due to which it is impossible to fix the retainer.

It is important to consider that the window limiter, installed in the leaf of the flap, can only be used for plastic windows. Its use in a wooden profile threatens wood cracking towards its fibers.

With this method of installation minimized the risks of violation of the tightness of the glass package, the frame deformation.

Manufacturers

Among the manufacturers of window limiters confidence buyers uses products Penkid.. These are cable limiters made of steel, the strength characteristics of which are worthy of admiration - they are withstanding pressure up to 550 kg. They cannot be broken, cutting with a knife or snack with pliers. The length of the cable is 200 mm.
Unrivaled German quality demonstrate ROTO limiters. Some of them producer gives a 10-year warranty. Plastic limiters of this brand are completely safe from the point of view of environmental friendliness, and metal have multilayer protection against corrosion.
High reliability is characterized by the accessories of another German brand Reha.u.

Modern plastic windows managed to prove to everyone and each of their high practicality and functionality. One of the main advantages of these windows is high tightness. But this is also a disadvantage: the fact is that the air in the rooms should be updated. For this, people open a plastic window in ventilation mode. It is convenient and comfortable in summer. But in winter it is not the best option. To solve this task there is a special window opening limiter. It allows you to open the sash only on a slight defined angle. Let's consider the main types and rules for choosing these accessories.

Functions of limiters

This small accessory is an element of accessories, which is installed in the sash and fix in a certain position. The sash is open. The design of the product is a small plank with slots in it.

The window is fixed using a special retainer. It is also needed to change the position of the open window in narrow limits - from 1 to 10 centimeters. The window opening stop bar is called a comb. When the window is equipped with such an accessory, it will suddenly fail under the influence of drafts, and will not appear due to the impacts of the wind.

Types for purpose

Comb is not the only similar accessory. Depending on the purpose, other options can be distinguished. So, the limiter is called the castle from children who does not allow to open the sash to the child.

There are limiters for opening windows with a cable. These accessories are designed to fix the sash at a certain angle. Using a handle equipped with a special lock, the window will not open with the standard way - this is also a kind of limiter. In addition to these articles, accessories are also isolated in the form of latchs on magnets. They are designed for sliding windows and doors.

Types of window comb

The opening limiter "Comb" is distinguished by materials from which this product is made. Plastic comb diffes available. Manufacturers make these devices in different shades, you can easily choose the desired color. But due to the characteristics of the plastic, the accessory of such a plan is not distinguished by high durability. Metal regulators are significantly more reliable, but are offered at higher prices.

At the same time reliability at a high level. It is better to overpay a little, but to buy the most high-quality and durable product, reviews. You can also highlight combined solutions. Plastic and metal is combined here. So, in some models, the comb plastic, but the retainer for it is metallic. In addition to the difference in manufacturing material, the fixtures are different and the type of fastening: under the window handle or to the end of the sash. Below will look at each option.

Comb under handle

These fixtures are a comb and a fixator in the form of a pint. The latter is installed under the window handle. Plastic comb is fixed on the fixed part of the frame. Depending on the design features, the part may rise or descend. In different positions it takes a minimum of space. This is the most convenient window opening limiter.

But there are accessories that do not fully rise or do not fall. They are less practical - the product will constantly cling to the curtains and create various obstacles during the operation of the window.

The comb can be plastic, but the retainer is better to select from metal. Plastic products are quickly wearing. When choosing it is worth paying attention to the holes for fasteners coincide with those on the door handle.

Grebelka in motion

This window opening limiter is set to the end part of the sash. The comb is mounted on a fixed frame. The installation site does not depend on what position is the handle or any other element. This allows you to place it anywhere. The pin is attached through a long self-drawing. The latter passes through the two jumpers of the navel in the sash. Only then can we talk about reliable mounting.

Features of different limiters

When you buy a window opening limiter from children with a key, you should find a place where the key will be kept constantly. There are big chances of losing it. If the window is partially closed and open, it is best to acquire a comb, rather than a handle with a lock and key. The comb will allow you to set up a small slot without the need to open the sash. Of course, the device is not suitable for families with children, since it does not provide reliable protection from the opening. But it allows you to conveniently and quickly adjust the desired angle.

Cable limiters are suitable for setting the desired opening angle both in horizontal and vertical planes. At the same time, open the window manner will not succeed. Choosing a comb, better stop the choice on metal window opening limiters. As already noted, they are much more reliable and have a good resource.

Penkid limiters

These accessories use good demand from consumers. This is a cable limiter. It is able to perform several tasks at once. This is blocking the window to protect against the opening of the sash, as well as protection against illegal penetration.

The design uses a thick cable from high-quality steel. It is impossible to cut with a simple hand tool. Cable length - 20 centimeters. This allows you to install the limiter in any convenient location. The sash can be opened at a distance of 10 centimeters. The design can withstand the pressure of 550 kilograms.

Penkid window opening limiter has a good configuration. It has everything you need to install. It:

steel rope;
plastic nozzles;
metal base and castle to it;
key;
four self-edge for installation;
instructions for installation.

Conclusion

As can be seen, there are quite a lot of such devices. To say which one is better, difficult. Each accessory solves its separate tasks. But to protect against window opening, you can purchase a metal comb, and it will be quite enough. If there are children in the family, then it is not necessary to do without a lock with a lock.

Plastic windows have long proved their practicality and functionality. One of their main advantages is to ensure tightness. However, this can be considered a certain disadvantage, because the air in the room should be periodically updated. So you have to open windows for venting. In winter, it is not very convenient, and at another time of year too. Eliminate this task is a limiter to open plastic windows, which allows you to open the swinging sash only to a certain angle. Thus, the normal level of ventilation level will be achieved.

Purpose limiter

It is possible to define the device under consideration. Plastic window limiter — this is an element of accessories that allows you to install and fix the window sash in a certain open position. Constructively, this mechanism is a bar with slots, as well as the lock position of the sash. It allows you to change the position of the open sash window usually in the range of 1-10 cm. The slat regulating the degree of opening of the sash is also called the comb.

When such a device is installed on the window, the sash will not shut from the draft and will not swing completely from the impact of the wind.

Varieties comb for windows

The comb for PVC windows may vary depending on the material of the manufacture:

Limiters for windows also differ in the installation method: under the handle of the sash and in the removal (end) of the sash.

Combs with a fastening for a handle

Such a restricter for opening a plastic window consists of a comb and a pin (retainer), which is fixed under the window handle. Comb is mounted on a fixed frame. Depending on the design, the comb can omit or climb, occupying a minimum place in the lowered position. This is the most convenient option. Also there are combs that cannot be fully raised or lowering, tightly pressed against the frame. They are less convenient, as they constantly cling to the curtains, create obstacles near the window.

The lock for windows is better to choose metallic, as the plastic product can be broken very quickly. When choosing a retainer, it is necessary to pay attention to that its holes coincide with the screw holes in the handle.

Grooms with fastening in motion cast

The block of sash of this type is attached not at the handle, but in the end of the sash. The comb's herself is traditionally fixed on a fixed frame. The place of attachment of such a limiter does not depend on the arrangement of the handle. This makes it possible to place it anywhere. For example, sometimes some element of the fittings are just opposite the handle, so it is impossible to fasten the retainer under the handle.

The pin mount is carried out by a long self-tapping screw, which should pass through both internal lintels of the nipper. Only in this case the fastening will be quite reliable.

Important: This opening lock for plastic windows cannot be installed on wooden sash. The efforts arising on the pintage are such that they can damage wood along its fibers.

Installing the limiter

Install the window limiter can be installed at any time, including the plastic windows that have long been operated. The design of the limiter provides. Especially such a simple mechanism, what is the comb.

Tools required for work

To protect against opening plastic windows or closing them, it is mounted correctly, before installing a comb, you must prepare the following tools and materials for work:

limiter (comb) with a pin;
markup tool (pencil);
drill with drills;
screwdriver "Cross" or a screwdriver with an appropriate bat;
self-tapping screws up to 13 mm long. Long tapping screws can not be applied, as they can damage the window profile.

Tip: If you install the limiter in the molding of the window sash, it is additionally sought out of self-sketch, the length of which would exceed the size of the retainer by 3 cm. After passing through the lock, the self suggests rigidly fixes it on the end of the sash.

Installation of the limiter with a fastening for a handle

Installation of the limiter with a fastening in the leaf

Pre-selected location for the installation of the limiter. Since the handle is not involved, the comb can be installed anywhere in the sash.
A comb is screwed to the frame. To do this, self-tapping screws up to 13 mm long.
With the closed position of the sash, the position of the retainer on the pressure of the sash is marked with a pencil. The latch should be located exactly opposite the comb, but at the same time so as not to interfere with the closing of the window.
A lock is screwed to the end of the flap (the hole is drilled under it).
Verification of the operation of the limiter.

Cons Compare with valves

Regulator of opening plastic windows, in addition to indisputable advantages, not deprived of some drawbacks. They must be taken into account in the decision-making process on the installation of the limiter, if there is a choice between them and the supply window valves:

This device is not an obstacle for young children. It can be easily open, after which access to the open window will be unlocked;
If the dwelling is on the first floor, the possibility of penetrating the semi-open window can take advantage of intruders. The comb is easily removed from the retainer, and the window sash opens outside;
If you forget about the open window in the cold season, then the probability of perching the room is great;
When fastening the sash to the retainer, the noise properties of the plastic window will not be ensured;

Compared to the comb, the window supply valves are deprived of these flaws. Fresh air enters moderate quantities, and the window itself remains closed.

If you decide to install the sash opening limiter on your window, you are guided by the recommendations listed above, consider all the installation nuances. In this case, the stopper will regularly serve you for a long time, and you will not be disappointed.

Window opening limiter (comb) for plastic, wooden, aluminum windows. Installation and sale in retail.

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

Types of window opening limiters.

The window opening limiters presented on the market can be classified as follows:
By material manufacturing - plastic and metal.
In appearance - Euro-combs and the USSR-Comb.
By destination - For conventional ventilation and for safe ventilation (such limiters are effective protection of children).
On this page of the site, it will be about metal window opening stops, if you are also interested in plastic limiters, go to the Grebelka page for plastic windows.

Window opening limiter for conventional ventilation.

Euro-comb metal (imported production).

Such a window opening limiter has a very useful possibility - displacement / turn to a small angle to the right / left. This allows you to mount the limiter at some distance from the sash, which can be useful in the future, when adjusting the sash. The pin with the rubber cambrick, so the opening limiter dresses it tightly, without a backlash, which means there will be no metallic rattling with wind gusts. The pin is to be attached by self-drawing in the removal of the flap, and not under the handle. Fastening the pin is reliably. But since to mount the pin you need to "spoil" the sash with two holes, we will call such a fastening vandal.

Repeat. The pin is attached by self-drawing in the removal of the flap, and not under the hand, therefore such a limiter should not be installed on wooden windows, since the tree may not withstand strong wind loads and cracks in the direction of the fibers (from the direction only seems strong, it has a groove under the seal).

Euro-rowing metal and plastic are not interchangeable:
1. The platform of the rowing attachment (the one where there are holes for self-tapping screws) is wider than that of plastic, 15mm instead of a 12mm, so it may not fit between the flaps.
2. Holes for the screws of the attachment, this opening limiter and plastic does not coincide.

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

The cost of the rowing without installation (from 1pc.) - 450rub
Cost of rowing with installation - 550 rub

Euro-comb metal (Russian production).

Material for the design of the window opening limiter - Metalmost, containing zinc, aluminum and copper. The most widely foundry zinc alloys are used in the automotive industry for casting carburetrators, pumps, frame speedometers, radiators lattices, hydraulic brake parts, various decorative parts.

The appearance is the same as in plastic Euro-comb, but more per position (5 fixations, and not 4). Color - Combship itself and pin The base is white, brown. Do not have the ability to displace / turn to the right / left. The limiter dresses on the pin without dense fixation, but it can be ensured by winding the scotch.

Disadvantages: Not only does it have the ability to shift to the right / left, but it will not even be ground, so it is possible to wear it on the pin (in the case of a swivel, not a folding opening) with a significant effort, which is likely to lead to the breaking of the pin (This is on plastic windows). And on wooden windows, over time, cracks may appear, in the place of fastening the rowing itself. To avoid this, you need not to wrap up to the end of the screws of fastening the opening limiter and hang out himself. But it is unlikely to be considered convenient use, because With the gusts of the wind, rattling is not excluded.

Where to apply such opening limiters:
1. The use of this rowing is justified on the windows of large sizes, which are used primarily in the hidden position in the areas with drafts to prevent slamming.
2. Suitable for any window to which are suitable for geometry (provided that our installation).

The cost of the rowing without installation (white) (from 1pc.) - 200 rub.
The cost of the rowing without installation (Cor) (from 1pc.) - 230 rubles.
Cost with installation (white) (without rattling and conservation of offset to the right / left) - 350 rub
Cost with installation (Cor) (without rattling and conservation of bias to the right / left) - 380 rub
Minimum order cost (with installation) - 2000 rubles.

USSR-comb. Metal (Russian production).

Window Opening Limiter Material Material - Steel, Painted Powder Powder. The limiter has five fixations. The width of the slot of fixation is 5.7mm. Color - white, pin-base - white. Have the ability to rotate / displacement to the right / left. Included in the kit can be with a base-base or without it (in this case, any screws can serve as a pint).

Disadvantages:
1. The first slot is significantly removed (it is approximately at the level of the second slot of the plastic Euro-rowing), so micro-taking is impossible. For a folding position, only the first two slots are available, and the second fixes the maximum folding. Moreover, since, the magnitude of the folding depends on the height and width of the sash, it may require that only one first slot will be available for fixing the sash in the crowded position.
2. The window opening limiter is extended, therefore, if the windowsill is narrow, and the handle is located at the head level, it is possible to injury when fixing a small opening.

Where to apply such opening limiters:
On windows that are mostly open in turning mode and when the maximum opening angle is required.

The cost of the rowing without installation without a pin (white) (from 1pc.) - 80 rubles.
The cost of the rowing without installation with the pin (white) (from 1pc.) - 160 rubles.
The cost of the rowing with the installation (with a pin) is 350 rubles.
Minimum order cost (with installation) - 2000 rubles.

Disadvantages of window opening limiters.

The disadvantages of the window opening limiters include:
1. The window remains fixed, but not closed. If the room is on the lower floors, it becomes available for an attacker.
2. For young children, this is not a window castle, but rather, something interesting, which must be touched and overcome.
3. Even if the sash is in the folding position, the air flow spreads not only vertically, but also horizontally and is located next to the window is not always pleasant and useful.
4. The window is open, and therefore all its noise protection properties disappear.
5. Even with the smallest of possible openings, the sash opens / lean over three sides of the perimeter and the total area of \u200b\u200bthe slit is obtained quite large, therefore, at negative temperatures, the room is quickly getting out. In winter, at night, you can hardly use the ridge, it will be very cold.

Valves of supply ventilation.

However, the need to access fresh air to the room remains at negative temperatures. Provide this access helps window ventilation valves.
About the supply ventilation in detail on the ventilation page of the windows, about the types of valves on the plug-in ventilation valves.
If you are going to solve problems with window valves, you are able to solve problems: fogging windows, stuffing rooms, "crying" windows, mold formation on window slopes, then enough valve average performance.
The problem of the obvious lack of fresh air, i.e. "To breathe" when closed windows, can be solved by setting the valves with a greater performance or multiple valves of average performance.

Window opening limiter for safe ventilation.

Opening limiter Aluminum window (Russian production).

Until recently, there was only one kind of window opening limiter for safe ventilation - Baby Safaty. But in 2011 a Russian limiter appeared, it leaves the window safe in a swivel and swivel position.

We are not for sale and not installed.

Metal opening limiter, for aluminum windows.

This opening limiter is set to "warm" aluminum windows and on the swing windows from the aluminum profile Provedal ("cold") and its analogs.
By quantity and "size" of possible fixations are similar to the USSR-comb.
Limiter - steel, on 5 fixations, color-white.
The pin is steel, white, installed under the handle.

For the possibility of installing the rowing, the following is important (please check):
- the appearance of the handle (presented in the photo),
- Dimensions of the base of the handle, they are: width - 27mm, height - 135mm,
- the principle of work of the handle - when turning the handle, the "pushers" converge and diverge (see on the other side of the open sash),
- Free space (on the frame) To install the limiter is the distance from the edge of the sash (opposite the handle) to the nearest something (wall, slope, adjacent sash, aircraft connection, etc.). There should be no free space - 18mm, since the width of the base of the limiters is 17mm.

If the appearance or size of the base of the handle (on your windows) others, and, in your opinion, install the limiter does not work, send a photo by mail, maybe something will come up.

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