Topaz Lighting Weatherproof Duct Seal Compound, Asbestos-Free

The Topaz Lighting Weatherproof Duct Seal Compound is a gray, asbestos-free sealing compound designed to close off conduit entries, duct openings, and cable penetrations against moisture, air infiltration, and pests. Commonly packaged in convenient pound-based quantities, including a 1 lb size, this pliable compound is a staple for electricians and contractors who need a dependable, non-hardening seal for indoor and outdoor electrical work. Its moldable consistency allows it to be pressed by hand into irregular gaps around conduit, cable, and duct entries, forming a weatherproof barrier that helps protect wiring systems from the elements.
