The Pemko 2891_S Heavy Duty Perimeter Gasket is built for the head section of door frames where a parallel arm closer or other hardware is needed. Additionally, it provides strong support while sealing out air, smoke, and sound, making it ideal for commercial and institutional doors.

Made with a durable aluminum retainer and a flexible silicone insert, this gasket is resistant to extreme temperatures, sunlight, ozone, water, and flame. Moreover, it is non-toxic, self-extinguishing, and impervious to fungus and mildew, making it perfect for areas that require frequent cleaning.

It is supplied undrilled in 36″ lengths or drilled in 80″ and longer lengths and includes PHSMS #6 x 5/8″ sheet metal screws for easy installation. If needed, it can also serve as a door stop, and flat head machine screws can be provided for countersunk #10 holes. Pemko can drill the head member if instructions are given at the time of order.
