Pemko 357SP84 84" 7' T Overlapping Astragal with Pile Galvanized Steel Finish

The 357SP84 T overlapping astragal seals the gap between double doors where they meet at the center. This 84-inch galvanized steel astragal with pile weatherstrip prevents air infiltration, light transfer, and moisture penetration through door assemblies. Pemko designed this overlapping meeting stile system to handle the thermal cycling and weather exposure that exterior double doors face daily.

The T-shaped profile overlaps both door edges when closed, creating a continuous seal along the full door height. The integrated pile weatherstrip compresses against the door surfaces to block drafts and improve energy efficiency. Mounting hardware comes included for field installation on new or retrofit door projects.

This astragal meets UL 10C positive pressure fire testing standards and UL 1784 air leakage requirements for door assemblies. ASTM E283 air infiltration compliance supports building envelope performance requirements.

Fire-rated door assemblies require regular inspection per UL 10C testing protocols to maintain their listings. For buildings with specific egress requirements, review NFPA 101 Life Safety Code provisions that may affect door hardware selection and maintenance schedules.
