Pemko 18061CNB48 48" 4' 180 Degree Aluminum Retainer Weatherstrip with 5/8" Nylon Brush Clear Aluminum Finish

This aluminum retainer weatherstrip with nylon brush seal mounts around door frames to block air infiltration and weather penetration. The 180-degree design wraps around door frame corners and edges where standard straight weatherstripping cannot reach. Pemko engineered this brush seal to compress against door surfaces while maintaining flexibility to accommodate surface irregularities and door movement.

The densely compressed 5/8" nylon brush flexes to maintain contact as doors open and close. The aluminum retainer measures 3/4" in height with the brush extending another 5/8" for total coverage of 1-3/8". This 48-inch length covers standard single door frames. Clear anodized aluminum finish resists corrosion in exterior applications while blending with most door hardware finishes.
