Plastic Widowhood Fronts are made out of high density polythene, and having more material in each front, the polythene is more pliable, so when it is cold they are less likely to break. New improved blocks with extra screw holes. All fittings included except screws. Size: 30 1/4" X 14 1/4" (including fittings)
