Marvin's sliding French door is available with extruded aluminum cladding that is durable, long lasting, measurably thicker and stonger than thin roll-form aluminum or vinyl cladding. Coated with Marvin's high performance finish, it has the beauty of wood without the upkeep. It features the styling of a classic French door with its 4 3/4-in stiles and top rails and 8 1/8-in. wide bottom rails. With a multipoint locking system, the sliding French door can withstand 1200 lbs. of force. Full weatherstripping seals the frame and door panel when locked.
