4 Bar Hinge Stops

This adjustable stop is intended for use on 4 bar hinges. It is a simple stop plate which is inserted into the hinge track and uses an outside hold down screw. The design of the plate allows it to be positioned anywhere along the track to provide an infinite number of stop positions. The unique outside hold down screw allows access to the stop with the window only cracked open a small amount. Once installed, it will pass the ASTM F2006 limited opening standard.
