The cavity closing wedges are designed to provide both the correct closing position of the hinge side of the push out casement window and, in some situations, to enable the window opener to close snugly onto the weather sealing gasket. The wedges are designed in such a way that when the two opposing sections come together, they tighten both the vent sash and the uPVC outer frame.
Depending on the profiles used and how close the two components come together within the cavity once closed, a packing shim beneath may be required to draw the two parts together.
