Steel City 52141 1/2 Outlet Boxes

It's a 4 inch square steel box, 4 x 4 x 1-1/4 inches, with 18 cubic inches of capacity. That volume is what decides your conductor count under box fill rules, so figure it before you add devices, clamps, and grounds.

Yes. At 1-1/4 inches deep (31.75 mm) the 52141 1/2 sits well inside the 3-1/2 inch depth of a nominal 2x4 stud, leaving room behind for conduit or cable. A 2x4 wall is 3-1/2 inches deep in actual dimension.

No. The Steel City 52141 1/2 is a steel square box carried as non-weatherproof, so it belongs in dry interior wall and ceiling work. For an exterior device location, the Mulberry Royal Mountie weatherproof outlet box is a die-cast aluminum 1-gang weatherproof box, and the Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs for surface conduit runs outside.

The 52141 1/2 is a standard steel outlet box listed to UL E2969 and is not an explosionproof enclosure. For classified locations, Appleton's malleable iron explosionproof conduit outlet boxes cover that duty: the GRJ Series and the universal GRJS Series, plus the GRT75 malleable iron round conduit outlet box for round-cover applications.

It mounts to a wall or ceiling surface or structure and has 15 knockouts, so you have plenty of choice for running conduit or cable connectors in from the sides and back without rotating the box.

Yes, it carries UL file E2969.

The 52141 1/2 is configured for one outlet, so a single device with a square-to-single-gang plaster ring is what it's built for. If you need two or more devices side by side, go to a multi-gang box such as the Cantex EZ Series PVC multi-gang residential box or a 2-gang conduit box like the Thomas & Betts 2IH3-1 Red-Dot.

The 52141 1/2 ships as the box itself. A 4 inch square box takes a separate flat cover or a square-to-device plaster ring sized to your wall finish depth, so add that to the order along with your connectors.

They are not interchangeable. The 52141 1/2 is a square steel single-outlet box, 4 inches by 4 inches by 1-1/4 inches deep with 18 cubic inches of capacity and 15 knockouts, so it accepts metal conduit or cable connectors at those knockouts. The Cantex EZ Box is a PVC multi-gang residential outlet box, a nonmetallic multi-gang device box rather than a single-gang-depth metal box.

That is not its role. The 52141 1/2 is an 18 cubic inch square steel box for general wall and ceiling mounted outlets. A dedicated appliance outlet uses a purpose-built box such as the Pass & Seymour P242RRD thermoplastic range and dryer box.

Standard carton quantity is 50 boxes. Weight runs 62.5 lbs per 100 boxes, and the shipping carton measures 20.75 x 9 x 7.625 inches. Useful numbers if you're staging material for a multi-unit rough-in.
