Pemko S773W20 240" 20' Adhesive Perimeter Gasketing White Finish

The S773W20 adhesive perimeter gasketing seals gaps around door frames to block air infiltration, light transfer, and sound transmission.

The triple-fin design creates multiple seal points that stop drafts and reduce noise complaints.

Pemko built this gasket for quick installation with included adhesive backing. No mechanical fasteners needed. The silicone material stays flexible in temperature swings and maintains seal integrity over years of door operation.
