Hole seal for .87 in openings

The HOFFMAN AS050SS conduit hole seal closes unused pushbutton or conduit holes measuring .87 in diameter. It is made from 304 stainless steel for corrosion resistance in electrical enclosures. Installers use it to maintain the integrity of a sealed box when a knockout is no longer needed.

Verify the knockout diameter

Confirm that the hole in your enclosure measures exactly .87 in before ordering. The seal is designed for a .5 in conduit size and fits standard pushbutton cut-outs. Ensure the surrounding surface is clean and flat so the stainless steel flange seats properly.

Stainless steel construction seals the opening

The 304 stainless steel body resists rust and chemical exposure better than plated alternatives. No gasket or separate hardware is included; the seal installs directly into the prepared hole. This single-piece design eliminates loose parts that could fall into the enclosure.
