Hole Seal for 2.5 Inch Openings

This Hoffman AS200SS seal closes unused 2.5 inch pushbutton or conduit holes in electrical enclosures. It is made from 304 stainless steel for corrosion resistance in demanding environments. The component suits industrial maintenance teams and panel builders who need to maintain enclosure integrity.

Simple Press Fit Installation

The seal installs by pressing into the prepared hole without tools or fasteners. Correct hole diameter is critical because an oversized opening prevents a tight seal. Debris or paint on the hole edge can also compromise the fit and allow ingress.

Rated for 2 Inch Conduit Holes

The seal is designed specifically for 2 inch conduit knockout sizes with a 2.50 inch hole diameter. It does not adapt to other conduit sizes or thread types. Users requiring different hole diameters must select a separate seal model.

Questions about this item

How can I confirm the 2.50 in hole seal is properly seated after installation?

The stainless steel seal sits flush when the 2.5 in diameter matches the cutout; a snug fit with no visible gap around the edge shows it is sealing the unused conduit or pushbutton hole as designed.

What comes with the AS200SS and what must I supply?

The package contains the single 304 stainless steel hole seal for a 2 in conduit opening; no gasket, fasteners or tools are included, so have the correct drill or knockout punch ready for the 2.5 in cutout.

Which version of the Hoffman conduit hole seal should I select for a 2 in conduit?

Choose the AS200SS model — it is sized for a 2.5 in hole diameter and 2 in conduit, made from 304 stainless steel, and matches the listed specifications for that conduit size.
