Pemko PK33BL17 204" 17' Adhesive Perimeter Gasketing Black Finish

The PK33BL17 perimeter gasket seals gaps around door frames to prevent air infiltration and energy loss in commercial buildings. This adhesive-mounted weatherstrip installs on door frames and jambs where traditional mechanical fastening is not practical. The 3/8" wide PemkoPrene gasket from Pemko reduces HVAC costs by blocking drafts while maintaining extremely low door closing force for smooth operation.

The PK33 series design works specifically with tighter door frames where bulkier gasketing cannot fit. Installation requires only surface preparation and adhesive backing removal. The black PemkoPrene elastomer maintains flexibility across temperature ranges while resisting compression set. This 17-foot length covers most standard door openings with minimal waste.

This gasket meets UL 1784 air leakage standards, UL 10C fire door assembly requirements, ASTM E283 air infiltration testing, and ANSI/BHMA A156.22 door gasketing specifications. GREENGUARD Gold certification ensures low chemical emissions for indoor air quality.

Fire-rated door assemblies require gasketing that maintains UL 10C positive pressure testing compliance during annual inspections. For broader building code context on egress requirements, see NFPA 101 Life Safety Code standards.
