Pemko 315CN48 Door Bottom Sweep 48 in Neoprene Clear Aluminum

Product Description

The PEMKO 315CN48 is a door bottom sweep designed to seal the gap between the bottom of a door and the threshold, blocking drafts, dust, insects, and light infiltration. It ships in a clear aluminum finish and uses a 7/16-inch neoprene insert as the sealing element. At 48 inches in length, it fits standard 4-foot door widths. The unit measures 48.5 inches long, 1.75 inches wide, and 1 inch tall and weighs 0.7 pounds. Sold individually, it is installed by finish carpenters, door hardware specialists, and general contractors on both new construction and retrofit applications.

This door bottom sweep is suited for residential and light commercial entry doors, interior doors, and equipment room doors where a reliable bottom seal is needed. The neoprene insert provides flexibility and compression to maintain contact with uneven thresholds or floors. It is a practical fit for projects requiring weatherstripping, sound attenuation, or pest and smoke control at the door bottom.

Installation Notes

This sweep is typically installed by finish carpenters or door hardware technicians using a drill and appropriate screws for the door material. Close and latch the door before marking the sweep position to ensure proper neoprene contact with the floor or threshold surface. Do not overtighten fasteners, as this can bow the aluminum extrusion and reduce seal effectiveness. Verify the floor surface is level and that the neoprene insert does not drag to the point of restricting door swing.
