The cavity closing wedges are purpose made and comes as a part to fit to the opening window sash & has a raised lug that meets the opposing frame part which has a lower lug on it (see the technical drawing) Provides both the correct closing position of the hinge side of the push out casement window, and will also in some cases where the window opener is not closing tightly onto the weather sealing gasket also enable it to do so. The wedges are shaped and as described on this pairing has 1 part with a higher protruding lug than the opposing side so that as the 2 opposing parts close together they tighten both the vent sash to the upvc outer frame. Generally the sash part uses the higher protruding lug however you may find that the fabricator decided to use the lugs the opposite way round as they felt this gave a better seal performance.
Dependent on the profiles fitted and how close the 2 parts come together within the cavity once closed there may be need to adjust / create a packing shim under to pull the 2 parts together.
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 align the fixing point for 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.
