Steel City 72171 1 – Frequently Asked Questions
1) What size conduit knockouts does the Steel City 72171 1 box have?
It comes with combination 1/2 and 3/4 inch knockouts plus 1 inch knockouts, 13 in total across the sides and back. The combination openings mean you can land either 1/2 or 3/4 inch EMT or rigid connectors in the same hole without an adapter, and the 1 inch openings take a larger feeder run into the same box.
2) Is this box UL listed for commercial work?
Yes. The 72171 1 square steel box carries UL file E2969, which is the listing inspectors look for on a steel outlet box used in a commercial or institutional installation. It is also made in the United States, which matters on Buy American and federally funded jobs.
3) Can I mount receptacles or switches directly in this 4-11/16 square box?
Not directly to the box ears alone. A 4-11/16 square box is used with a separate device cover: a single or two-gang raised plaster ring for devices, or a flat blank cover when it serves as a junction box. The cover is ordered separately from the box, so plan a ring per box and match the ring depth to your wall finish thickness.
4) Can this steel box be used outdoors or in a wet location?
No. This is a knockout-style steel outlet box for dry interior work in walls, ceilings and exposed conduit runs indoors. For outdoor or wet locations use a gasketed weatherproof or cast box instead, such as the Mulberry Royal Mountie die-cast aluminum weatherproof box for a single device, or a Thomas and Betts Red-Dot 2IH3-1 two-gang conduit box with three 1/2 inch hubs where you are running conduit outside.
5) What should I use instead of this box in a hazardous or classified area?
A standard steel knockout box is not rated for classified locations. For Class I or II areas use an explosionproof malleable iron conduit outlet box: the Appleton GRJ Series and the Appleton GRJS universal box are explosionproof malleable iron outlet boxes, and the Appleton GRT75 is a malleable iron round conduit outlet box. The 72171 1 is for ordinary indoor locations only.
6) Is this box sold individually or in a case?
The 72171 1 is sold each, so order one per opening. If you are stocking a residential rough-in instead, non-metallic options like the Cantex EZ Series multi-gang PVC box cover that work; this steel box is the choice where you are running EMT or need the metallic raceway for grounding continuity.
7) Will a 240V range or dryer connection fit in this box?
The 42 cubic inch capacity is enough volume for a large-conductor pull, but a range or dryer outlet is normally installed in a purpose-built box with the receptacle integrated. For that use the Pass and Seymour P242RRD thermoplastic range and dryer box. Keep the 72171 1 for junctions, feed-throughs and standard device locations on conduit.
