Frequently Asked Questions

Security restricted friction stay hinges are designed to control how far a window can open while still allowing ventilation. They improve both window safety and home security.

A 16-inch side hung hinge is commonly fitted to larger uPVC or aluminium windows. It provides smooth opening action, reliable support, and controlled window movement.

Restricted hinges help prevent windows from opening too far, reducing the risk of falls and limiting external access. They are ideal for homes with children, apartments, and upper-floor rooms.

Compatibility depends on factors such as window size, sash weight, frame material, and existing hinge dimensions. Always compare measurements before replacing your hinges.

If your window becomes difficult to open, doesn’t stay aligned, or no longer closes securely, the hinges or mechanism may be worn out. If you need help choosing the correct replacement hinge, feel free to contact us for expert advice.
