Pemko 321CN36 Door Bottom Sweep Neoprene Clear Aluminum 36in

Product Description

The PEMKO 321CN36 is a door bottom sweep designed to seal the gap between the bottom of a door and the threshold or floor surface. It features a neoprene insert that compresses against the floor to block drafts, dust, light, and sound infiltration. The clear aluminum body provides corrosion resistance and a clean, low-profile appearance suited to commercial and residential applications. At 36 inches in length, it fits standard single door openings. Installation is handled by door hardware specialists, general contractors, or experienced maintenance technicians.

This door bottom sweep is appropriate for interior and exterior door applications where weathersealing, sound attenuation, or basic smoke and draft control is required. It mounts to the face or bottom of the door and requires no threshold modification. Typical applications include commercial office doors, institutional facilities, and residential entry doors where a clean aluminum finish is specified.

Installation Notes

Installation is typically performed by a door hardware technician or skilled maintenance professional. The sweep mounts to the door face or bottom rail using screws; ensure the door is removed or held stationary during fitting for accurate alignment. Verify door clearance from the floor before installation to confirm the neoprene insert will contact the surface evenly along the full sweep length. Follow applicable building and fire code requirements when installing door bottoms in rated door assemblies.
