Pemko S88BL21 Adhesive Perimeter Gasketing Black

Product Description

The PEMKO S88BL21 is an adhesive-backed perimeter gasketing strip in a black finish, designed to seal the perimeter of door frames against air, light, dust, and drafts. At 252 inches (21 feet) per package, it provides enough material to seal a full door opening on most standard commercial and residential applications. The pressure-sensitive adhesive backing allows for tool-free installation directly to door stops and frames. This product is part of a weatherstripping line with smoke and fire labeling credentials, making it a reliable choice for life-safety and energy-efficiency applications.

Perimeter gasketing like the S88BL21 is used on both interior and exterior door applications where a continuous perimeter seal is required. It is commonly installed on wood, hollow metal, and aluminum frame doors in commercial buildings, multifamily residential units, and institutional facilities. The black finish blends with dark-colored frames and door stops. Installers typically specify this product for air infiltration control, light gap elimination, and as a component in smoke- or fire-rated door assemblies where a labeled gasketing product is required.

Installation Notes

Installation is typically performed by a door hardware specialist, finish carpenter, or general contractor. Clean and dry the frame surface thoroughly before applying the adhesive-backed gasket to ensure proper bond. No power tools are required; a utility knife and tape measure are standard. For fire- or smoke-rated assemblies, verify that the gasketing label rating meets the requirements of the rated door assembly per applicable building and life-safety codes.
