WeatherBlock Brush Dock Leveler Seal Kit, 1" Brush w/ EPDM Fin Insert

The WeatherBlock Brush Dock Leveler Seal Kit provides a complete solution for sealing loading dock leveler gaps against drafts, wind-driven rain, dirt, dust, pests, and debris. Designed for loading dock levelers with gaps less than 1 inch wide, this complete kit includes two heavy-duty 8-foot galvanized weldable channels, standard 1-inch 90° aluminum retainers, and a 1-inch WeatherBlock brush seal with an integrated EPDM rubber fin insert. The weld-on design creates a durable, long-lasting weather seal for demanding commercial and industrial loading dock applications.

Unlike traditional brush seals or rubber seals alone, the WeatherBlock seal combines durable polypropylene brush bristles with a flexible EPDM rubber fin to provide two layers of protection. The brush blocks drafts while remaining flexible in cold weather, and the EPDM fin helps stop wind-driven rain and moisture. Together they help improve energy efficiency, reduce air infiltration, discourage pests, and keep debris from falling into the dock pit.
