The WIEGMANN WAS150SS hole seal is made of grained stainless steel in silver finish. It fits 1.5-inch maximum hole diameter for 1.5-inch conduit knockouts. Includes a quick wing nut for tool-free installation. Rated NEMA 1 for indoor use. Manufacturer part number WAS150SS.

How to install a WIEGMANN hole seal in a knockout?

To install a WIEGMANN hole seal, insert the seal into the knockout opening from outside the enclosure.

Always verify NEMA rating compatibility before installation.
