Cockspur Wedges
Cockspur Window Handle Wedges. These striker plates or wedge blocks are used to keep the window closed tightly to stop draughts. Found on the older types of uPVC and aluminium double glazed windows. Available in different thicknesses in 1mm increments from 2mm to 10mm! The lugs are generally standard fitting i.e. 31mm centres and can be prised from the window and pushed back on again! Remember if you purchase any of our cockspur handles the wedge is only £0.12 each + vat (one per handle).
