Window Lock With Swing Arm And 3 Ventilation Levels

This window lock with swing arm is designed to limit how far a compatible window or door can be opened. It can be used for controlled ventilation, allowing fresh air without the opening being completely free. The construction consists of two self-adhesive brackets and a movable arm that connects the frame and sash.

The lock has three adjustable positions, allowing the opening distance to be customised as needed. The rotating joints make the arm usable on several types of windows and doors, including inward-opening, outward-opening, and sliding models, when the mounting surfaces and direction of movement are suitable.

Key Benefits

• Limits the opening and allows for more controlled ventilation.
• Three adjustable levels enable the selection of different opening distances.
• Movable joints can rotate up to 360 degrees for flexible placement.
• Self-adhesive mounting generally does not require drilling.
• Can be used on compatible windows, sliding solutions, and doors.
• Can serve as an additional child safety measure in the home.
• The trigger must be operated before the arm can be moved from the selected position.
• Total length of approximately 36.5 cm provides reach between mounting points.

Overview

This window lock for child safety and ventilation works by mounting the main bracket on one surface while the end bracket is placed on the movable part. When the window or door is opened, the swing arm follows the movement and stops at the selected locking position.

The main bracket has three marked levels. The arm can be moved between positions, allowing the opening to be adjusted according to the room’s needs. The product can be used, for example, in kitchens, living rooms, bedrooms, or other areas where a limited opening is wanted. The long arm also allows for mounting on constructions where the brackets cannot be placed very close to each other.

The lock can help reduce the risk of small children fully opening a window or door. It does not replace supervision, approved safety brackets, or other necessary safety measures. Always check the installation before use.

Dimensions And Specifications

Controlled Opening In Three Positions

The three locking positions allow for changing the opening distance without disassembling the product. Choose the position that suits the desired ventilation and ensure that the arm is locked correctly. The actual opening depends on the window’s construction, hinges, and the placement of the brackets.

Mounting Without Drilling

1. Check that both mounting surfaces are flat and sufficiently wide.
2. Thoroughly clean the areas and allow them to dry completely.
3. Test the placement so that the arm can move without hitting handles or frames.
4. Remove the protective film from the self-adhesive surfaces.
5. Press the brackets firmly with even pressure.
6. Allow the adhesive to set before the lock is put under load.
7. Carefully test all three positions before regular use.

The main bracket requires a mounting surface of at least approximately 4.5 cm, while the end bracket requires at least approximately 3.8 cm. The adhesive strength depends on the material, cleanliness, and texture of the surface. The product should not be mounted on loose, porous, damp, or uneven surfaces.

Daily Use And Inspection

Regularly check that the brackets are secure and that the joints, trigger, and arm are functioning correctly. Stop use if any parts become loose, damaged, or deformed. Avoid hanging objects on the arm or using it as a handle.

This window lock with three levels is a practical solution for those who wish to combine a limited opening with the possibility of ventilation on compatible windows and doors.
