ExpertThis is a purpose made unique cavity closing wedges that uses a shaped metal spring wedge on the opening window side that slides onto the heavy duty nylon wedge plate on the opposite frame side of the window and is designed to help both the correct closing position of the hinge side of the push out casement window, and also in some cases where the window opener is not closing tightly onto the weather sealing gasket also aid it to do so. The wedges are shaped so that as the 2 opposing parts close together they tighten both the vent sash to the upvc outer frame.
The clever metal shaped plate allows it to slide and also flex and pivot to create a tight weather seal and is designed to be almost universal to fit many of the differnt Upvc window systems used over the years.
Fitting tip: Fit the first half of the wedge onto the opening sash into the euro-groove slot then mark the centre of this onto the edge of the sash so that you can transfer this to the outer frame to mark the fixing point for the 2nd half otf the opposing wedge. It is always worth checking that the 2 profiles are level and not bowed out of shape as this may cause the 2 parts to not locate correctly and actually increase the gap not close it. Dependant on the shape of your upvc profile you may need to remove / cut back with a sharp wood chisel / stanley knife to allow the frame part to sit flat and securely on the profile.
