Hubbell SS33 Blank Box Mount Plate

The Hubbell SS33 is a stainless steel wall plate designed for box mounted installations in commercial and industrial settings. It provides a durable cover for unused electrical boxes. The construction uses corrosion resistant materials suitable for demanding environments. A protective plastic film guards the finish during handling and installation.

Suited for corrosive or high abuse areas

This plate fits projects requiring non magnetic 302/304 stainless steel with 18.0% chromium and 8% nickel content. It serves hospitals, food processing plants and static sensitive zones well. Buyers needing magnetic 430 type steel with 17.0% chromium for standard commercial use should look at something else. Those wanting brass or anodized aluminum finishes will need a different product.

Covers a single gang opening

The blank design closes one electrical box completely without cutouts for switches or receptacles. It handles exposure to moisture, cleaning chemicals and physical impact in heavy duty applications. The plate offers no openings for devices so it cannot accommodate switches, outlets or data jacks. Installers requiring device cutouts must choose a different configuration.

Questions about this item

Does the SS33 blank plate fit a standard US single-gang box without an adapter?

Yes, the SS33 is a box-mounted wall plate designed to attach directly to a standard single-gang electrical box using the included mounting holes.

Can I install this stainless steel plate next to older plastic or metal plates without a visible mismatch?

The SS33 uses 302/304 stainless steel with 18.0% chromium and 8% nickel, giving a consistent brushed finish that coordinates with existing plates of similar grade.

How do I confirm the SS33 is properly secured and grounded after mounting?

Tighten the mounting screws until the plate sits flush against the wall; the metal-to-metal contact with the grounded box provides the required ground path.
