Pemko 303AS84 84" 7' Standard Perimeter Gasketing with Silicon Mill Finish Aluminum Finish

The 303AS84 standard perimeter gasket installs around door frames to create weathertight seals that prevent air leakage and improve energy efficiency. This 84-inch aluminum frame gasket with silicone insert mounts to the door frame perimeter on exterior and interior applications where air infiltration control is critical. Pemko designed this gasket to address building envelope performance requirements while maintaining door operability.

The anodized aluminum frame holds a flexible silicone insert that compresses against the door when closed. The mill finish aluminum provides corrosion resistance for long-term performance. Mounting hardware comes included for direct frame installation.
