The PK55BL17 is a 204-inch adhesive perimeter gasket that seals air gaps around door frames to prevent energy loss and smoke infiltration. This Pemko PemkoPrene elastomer gasket installs on door frames where tight clearances require low closing forces. The 1/2-inch wide profile compresses easily while maintaining effective weatherization and smoke control.
The adhesive backing eliminates screws or fasteners for quick installation on metal or wood frames. The black PemkoPrene material resists weathering and maintains flexibility across temperature ranges. This gasket works on both fire-rated and standard door assemblies where air sealing is required.

This gasket meets UL 10C positive pressure fire testing standards and UL 1784 air leakage requirements for door assemblies. It also complies with ANSI/BHMA A156.22 door gasketing standards and ASTM E-283 air infiltration testing. GREENGUARD Gold certification ensures low chemical emissions for indoor air quality.
Fire-rated door assemblies require annual inspection per NFPA 80 standards, and proper gasketing is critical for UL 10C fire-rated doors to maintain their listing. For egress door applications where occupant loads require specific opening forces, see NFPA 101 Life Safety Code requirements for exit door hardware compatibility.
