Duct Seal Compound - 1 lb Plug

This compound seals conduit openings against drafts, dust moisture and noise. It also protects terminal boxes, pot heads and bushings from corrosive elements and deadens switch gear panel noise. The dough-like compound is easily "thumbed" over holes and gaps. It will not harden or form a skin under normal conditions.
