The 57AV36 door bottom sweep mounts to the bottom rail of exterior doors to seal gaps up to 7/8" between the door and threshold or floor surface. This Pemko surface-mounted weatherstrip prevents air infiltration, water penetration, and energy loss at the door bottom. The triple fin vinyl gasket design conforms to uneven surfaces and irregular thresholds, making it ideal for outswing doors where perfect surface contact is difficult to achieve.
The sweep features anodized aluminum construction with mill finish and mounting hardware included. The Eco-V triple fin design flexes to maintain contact across surface irregularities while providing consistent weatherization performance. Installation requires surface mounting to the door bottom with screws through the aluminum extrusion.
