The 3151CN36 door bottom sweep installs on the interior face of doors to seal gaps up to 1 inch between the door and threshold or floor. This surface-mounted sweep prevents air infiltration, light penetration, and controls smoke migration in commercial buildings. Pemko designed this 36-inch sweep with slotted mounting holes for field adjustment and a durable EPDM gasket that compresses to seal irregular floor surfaces.
The clear anodized aluminum housing resists corrosion while the EPDM extrusion provides outstanding resistance to abrasion, hydraulic fluids, alkalis, heat, ozone, and weather. The sweep reduces infiltration of wind, rain, and snow while maintaining effective sealing performance across temperature extremes. Mounting hardware comes included for straightforward installation on wood or metal doors.
