This 36-inch door bottom sweep installs on the bottom rail of doors to seal gaps up to 1 inch against dust, light, smoke, fire, and insects. The concealed fastener design provides a clean appearance while the anodized aluminum retainer with snap-on cover delivers durability in high-traffic applications. Pemko builds this sweep with a 1-inch nylon brush that conforms to uneven floor surfaces, making it ideal for exterior doors and areas requiring weatherization.
The aluminum casing withstands repeated door operation without warping or cracking. Mounting hardware comes included for straightforward installation on new construction or retrofit projects. This door bottom effectively blocks air infiltration to improve energy efficiency and indoor comfort control.
