This restrictor is designed to restrict the opening of windows to provide both safety and security and can be fitted to almost any window or door material, and virtually any style.


When fitted correctly, the window opening should not exceed 10cm; the reccomended opening to prevent falls.


The cable can be released by pushing the button on the lock body and withdrawing cable when required to open the window fully. The button can be locked with the key to ensure that the button stays in the locked position when required. When in the locked position the button will not depress.

The unique feature of this restrictor allows the bullet to engage in the lock body even if the button is in the locked position.

Our cable restrictors have been independently and rigorously tested to BS 6375-2 2009BS EN 14351-1:2006 Accreditation for Windows and Doors.
