For use with concealed of exposed hinges, our Snubbers prevent bowing of tall casement windows, or wide awning windows and have been found to be useful with double-hung windows in improving the seals of the bottom and top rails in the closed position.
Two models feature a PVC insert for use on aluminum clad units. This PVC insert reduces wear on the finish of the cladding
Also available is a Concealed Snubber which fits between the sash and frame in a 14 series hinge cavity. This hardware eliminates the product from being visible on the exterior of the window.
