The 3024GP is built to a 28 x 22 x 22 inch envelope, so size your enclosure interior against those figures before ordering. It is a NEMA panel adapter from the Premier series accessory line, meant to mount a subpanel or gland plate inside an enclosure rather than being an enclosure itself.

UL Listed, yes. That is the rating carried on the 3024GP panel adapter, which matters on institutional and industrial jobs where every item inside the enclosure has to be a listed component at inspection.

Both. The plate is stainless steel with a white polyester powder coat over it, so you get the corrosion resistance of stainless plus a light reflective interior surface that makes it easier to see component labels inside a deep enclosure.

Order it as B-Line part 3024GP. That single model covers the white powder coated stainless version of this Premier series panel adapter, so there is no finish or size suffix to specify.

The substrate is stainless steel, which is the material spec'd for food processing, washdown, and coastal or chemical exposure where plain carbon steel plate rusts at every drilled hole. The white polyester powder coat sits over that stainless base rather than being the only barrier, so a drilled or cut edge still leaves stainless exposed, not bare mild steel.
