Pemko S773BL20 240" 20' Adhesive Perimeter Gasketing Black Finish

The S773BL20 adhesive perimeter gasket seals the gaps around door frames in hotel rooms, office spaces, and other commercial buildings. This 240-inch black silicone gasket prevents air leakage, sound transmission, and light infiltration through door perimeters. Pemko designed this triple-fin gasket specifically for hospitality applications where room-to-room sound control matters most.

The adhesive backing mounts directly to door frames without mechanical fasteners. The silicone material compresses against door edges to create an effective seal. Each 20-foot length covers standard door openings with material to spare for field adjustments.

This gasket meets UL 10C, UL 1784, ASTM E283, and ANSI/BHMA A156.22 standards. Fire door assemblies using this gasketing require UL 10C positive pressure testing to maintain their fire ratings. The product also carries GREENGUARD Gold certification for low chemical emissions in occupied spaces.

Installation involves cleaning the frame surface and applying the gasket around the door perimeter. For broader code context regarding building safety requirements, see NFPA 101 Life Safety Code egress standards.
