Pemko 5025ANB84 84" 7' Mortise Retainer with 1/4" Nylon Brush Mill Finish Aluminum Finish

The 5025ANB84 mortise brush weatherstrip seals gaps up to 1/4" around door perimeters and window frames. This 84-inch aluminum retainer with nylon brush insert blocks infiltration of air, wind, rain, snow, and light through building envelope gaps. Pemko designed this brush gasket to maintain optimal contact between the seal surface and the door or frame it seals against.

The mortise aluminum retainer mounts flush into routed channels while the 5/16" nylon brush flexes to accommodate surface irregularities and building movement. Custom cutting to specific job lengths reduces waste on installation. The mill finish aluminum provides corrosion resistance for exterior applications.

Fire door assemblies often require weatherstripping that won't compromise fire ratings, making UL 10C fire door testing critical for product selection. For broader code context on building egress requirements, see NFPA 101 Life Safety Code guidelines.
