Restrictor friction hinges are an essential element of home security; they limit window movement for added protection. Considered a multi-purpose solution, they also improve ventilation by enabling windows to be safely opened a few inches without being fully opened. This article provides a comprehensive guide to installing restrictor friction hinges on various window types.

Installation on Casement Windows

Casement windows swing outward and are typically found in homes and offices.

1. Identify the Hinge Location: Determine the hinge side of the window frame where the restrictor friction hinge will be installed. Mark its location with a pencil.

2. Prepare the Hinge Site: Drill a pilot hole at the marked location and insert the included screw. Ensure the screw is flush with the window frame.

3. Attach the Hinge: Align the hinge with the prepared site and secure it using the remaining screws. Tighten them firmly.

4. Adjust the Friction: Once the hinge is installed, adjust the friction level to your desired resistance. Use a screwdriver to turn the adjustment screw on the hinge accordingly.

Installation on Sliding Windows

Sliding windows move horizontally along a track and are common in commercial buildings.

1. Select the Restrictor Fit: Choose a restrictor friction hinge that is compatible with the sliding window’s track design.

2. Measure and Mark: Measure the distance from the window edge to the desired opening limit. Mark the opening position on the sliding track.

3. Position the Restrictor: Align the restrictor friction hinge with the marked location on the track. Ensure it does not interfere with the window’s movement.

4. Fix the Screws: Use self-tapping screws to secure the restrictor to the track. Tighten them properly to prevent any movement.

Installation on Tilt-and-Turn Windows

Tilt-and-turn windows offer both swinging and tilting capabilities.

1. Determine the Handle Side: Identify the side of the window that has the operating handle. The restrictor friction hinge will be installed on the opposite side.

2. Locate the Stay Arm: Find the stay arm protruding from the window frame. It helps hold the window in the tilt position.

3. Fix the Hinge: Position the restrictor friction hinge on the stay arm and secure it with the provided screws. Tighten them to ensure a secure fit.

4. Set the Restriction: Adjust the restrictor to set the desired opening angle for the tilt position. Rotate the hinge’s adjustment screw until the desired resistance is achieved.


Installing restrictor friction hinges on different window types is a crucial step towards enhancing home security and improving ventilation control. By following the specific instructions provided in this guide, you can effectively install these hinges on casement, sliding, and tilt-and-turn windows. Ensure proper alignment, secure fastening, correct friction adjustment, and proper operation to maximize their effectiveness. Restrictor friction hinges provide a practical and efficient solution for securing and controlling window openings, ensuring peace of mind and added protection.
