Protect your home and its occupants with our surface-mounted spring-loaded window restrictor, designed to enhance window security and safety without compromising on functionality. This discreet device limits how far a sash window can open — helping to prevent accidental falls, deter unauthorised access, and improve child safety in the home.

Equipped with a simple finger-release mechanism, the restrictor allows you to fully open the sash when needed. Once the window is closed, the spring-loaded catch automatically re-engages, offering hands-free safety every time — no need to manually reset it.

This feature makes it an ideal solution for rental properties and multi-occupancy buildings, where regulations or safety standards often require restrictors that automatically re-engage. It offers reassurance for landlords, tenants, and parents alike.

Important Compatibility Note:

This restrictor is designed for flush sashes or those with a low step. If your window has a deeper step, you may need to use a spacer to raise the spring catch for proper alignment. The Irish stockist supplies a clear, purpose-made packer that ensures a clean, secure installation on stepped sashes.
