The Xcluder 4" Rodent Blocker Bottom Seal is a heavy-duty door-bottom gasket designed to stop mice, rats, and crawling insects while sealing out drafts, dust, and light. Built for demanding residential and commercial applications, it’s used on overhead/roll-up, sectional, and garage doors where larger gaps or uneven floors require a taller door sweep. The integrated Xcluder fill—an internal stainless-steel fiber blend encased in a rugged gasket—creates a proven, gnaw-resistant barrier that helps improve energy efficiency and pest exclusion in warehouses, loading docks, retail spaces, food facilities, and home garages.
This replacement/upgrade seal is compatible with many standard aluminum retainers designed for 4-inch bottom gaskets. Installation is straightforward: cut to length, slide or insert into the door’s retainer/track, and adjust for consistent floor contact across the opening. The flexible gasket compound maintains a reliable seal across seasons, and the corrosion-resistant internal fibers won’t degrade from moisture exposure. For safety, wear gloves when handling, as the embedded barrier can have sharp strands. Routine inspection for wear, debris, and proper contact will ensure lasting performance. No electrical power or programming is required, and the product supports integrated pest management practices without pesticides.
