Pemko 303APK3684 36" 3' x 84" 7' Standard Perimeter Gasketing with Vinyl Mill Finish Aluminum Finish

The 303APK3684 is a standard perimeter gasket that seals the frame around commercial doors. You install this on door frames to block air infiltration and meet energy efficiency requirements. Pemko builds this 36" x 84" gasket with anodized aluminum carrier and vinyl insert to handle daily door operation while maintaining the seal.

This gasket mounts around the entire door frame perimeter using included hardware. The aluminum carrier holds up to heavy traffic while the vinyl insert compresses against the door to stop air leakage. The mill finish aluminum blends with most commercial frame finishes.
