Pemko 303AS3684 Perimeter Door Gasket 36x84 Silicone Aluminum

Product Description

The PEMKO 303AS3684 is a standard perimeter gasketing kit designed to seal the head and jamb of a door frame, blocking air, light, dust, and moisture infiltration. Finished in mill finish aluminum with a silicone bulb seal, this product is built for durability in commercial and residential door applications. The kit is sized for a 36-inch wide by 84-inch tall door opening and ships as a single unit. Licensed door hardware installers, glaziers, and finish carpenters are the typical trades that specify and install perimeter gasketing of this type. The silicone seal material offers long-term resilience against compression set and environmental exposure.

This perimeter gasketing is intended for standard single-door openings in commercial, institutional, and residential construction. It is installed on the door frame at the head and jambs to create a continuous seal around the door perimeter. The 36 x 84 inch sizing corresponds to a standard 3-foot by 7-foot door, which is among the most common commercial door configurations. The mill finish aluminum extrusion blends with standard aluminum frame systems. PEMKO is an ASSA ABLOY Group brand and produces gasketing products that carry sound, smoke, and fire performance designations across its broader product line.
