HOFFMAN AS400 Conduit Hole Seal 4.62 in

The HOFFMAN AS400 is a steel conduit hole seal designed to close unused pushbutton or conduit openings in electrical enclosures. It fits a 4.62 inch diameter hole and corresponds to a 4 inch conduit size. This component helps maintain the protective integrity of the box.

Suitable for 4.62 inch holes, not other sizes

This seal suits electricians and panel builders who need to blank off a specific 4.62 inch cutout in a steel enclosure. It is not for installers working with different hole diameters or those requiring non-metallic sealing materials for corrosion resistance.

4.62 inch hole diameter fit

The single specification that decides fit is the 4.62 inch hole diameter. The seal is manufactured to match this exact opening and the associated 4 inch conduit standard. Verify the enclosure cutout matches this dimension before ordering.

Questions about this item

Does the steel seal generate any heat or noise when installed in a conduit hole all day?

The steel seal is a passive component with no moving parts or electrical connections, so it produces no heat and makes no noise once fitted.

What additional hardware must I already have to fit this 4.62 in steel seal?

You need a 4 in conduit or pushbutton cut-out with a 4.62 in diameter opening; the seal presses into that hole and requires no extra fasteners or gaskets.

Will this seal work with older conduit boxes that have a 4.62 in knockout?

Yes, the seal is designed for any 4.62 in hole in steel boxes, so it fits legacy enclosures that match that diameter.
