Two-handed restrictor

Our two-handed operation window restrictor is designed to avoid accidental disengaging. There are no keys required for this restrictor and the device automatically re-engages when the window is closed. The added feature of green button enhancement signifies a fire exit. This restrictor fits inline with your friction hinges and also incorporates a run-up block to bring the opening window in line with the frame when closing.

With the restrictor fitted between the frames there are no unsightly attachments to be seen on the main surfaces of the window.

To disengage, simply slide the green buttons to the side.

Technical: The restrictors are tested to 50,000 cycles and resist an impact of 600N outward force.
