Spring Loaded Restrictor

A simple spring loaded window restrictor that if fitted correctly will re-locate to its restricted position each time the window is closed. To disengage the catch, to open the window fully, just requires a simple ‘flick’ of the restrictor arm. With the restrictor fitted between the frames there are no unsightly attachments to be seen on the main window surfaces. Can be used on aluminium, PVC or timber windows.

Technical: Resists an impact of 600N outward force.
