Purpose-built seal

The Wiegmann WAS050 is a carbon steel hole seal designed to close unused pushbutton or conduit openings in electrical enclosures. It fits a 0.87 in diameter hole and matches a 0.5 in conduit size for a precise, secure fit.

Replaces open knockouts

This seal upgrades an enclosure by covering exposed holes left after wiring changes or component removal. The jump is worth it when an installation must meet enclosure integrity requirements and prevent dust, oil, or moisture ingress through unused entries.

Suits panel builders and maintenance crews

It serves technicians who need a durable steel plug for standard conduit cutouts in industrial cabinets. Buyers who need a non-metallic seal, a different hole diameter, or a multi-hole cover plate should look at something else.
