Wiegmann WAS400 Hole Seal 4.64 in Steel

Wiegmann WAS400 4.64 in Hole Seal

The Wiegmann WAS400 is a carbon steel hole seal designed to close unused 4-inch conduit or pushbutton openings. It provides a secure barrier for electrical enclosures in industrial environments. The 4.64-inch diameter matches standard 4-inch conduit dimensions.

Suits 4-inch conduit closures, not other sizes

This seal fits builders and electricians closing 4-inch knockout holes in panels or junction boxes. It does not serve applications needing smaller or larger diameters, different materials, or threaded conduit connections. Buyers needing alternative dimensions should look elsewhere.

4.64-inch hole diameter is the critical spec

The 4.64-inch hole diameter determines compatibility with standard 4-inch conduit openings. Verify the knockout size before ordering. The carbon steel construction suits general industrial use where corrosion resistance is not the primary requirement.
