Pemko S88BL25 Adhesive Perimeter Gasketing 300 in Black

Product Description

The PEMKO S88BL25 is an adhesive-backed perimeter gasketing strip designed to seal the head and jamb perimeter of door frames. It ships in a 300-inch (25-foot) length with a black finish, making it suitable for installations where a clean, finished appearance is required. The pressure-sensitive adhesive backing allows the gasket to be applied directly to door frame surfaces without mechanical fasteners. This type of perimeter gasketing is used by door hardware installers, commercial glaziers, and finish carpenters to reduce air infiltration, limit dust and light transmission, and improve the overall seal of a door assembly.

Perimeter gasketing of this type is commonly installed on commercial and residential interior or exterior door frames. It applies to the head and jambs of the door opening to close the gap between the door stop and the face of the door when closed. The black finish blends with darker frame finishes and painted or dark-anodized door hardware. A single 300-inch roll provides enough material to seal a standard door perimeter with material to spare, reducing the need for multiple pieces on a single opening.

Installation Notes

Installation is typically performed by door hardware technicians or finish carpenters. Clean the door frame surface thoroughly and allow it to dry completely before applying the adhesive strip to ensure proper bonding. Cut the gasketing to length with a utility knife or shears before peeling the adhesive backing. No power tools or mechanical fasteners are required, but surface preparation is critical to long-term adhesion.
