Our Wedge-Style Aluminum Weatherstripping features a medium-duty extruded aluminum carrier that has notched sides for better fit and trouble-free installation. The Santoprene® sealing gasket stays pliable in sub-zero temperatures and won't crack, shrink or become brittle or stiff. This weatherstripping works well on warped and inconsistent doors. It also features slotted screw holes for easy adjustment and the kit includes screws.
