Steel City 56111 – Frequently Asked Questions

1) How deep is the Steel City 56111 4-inch round box, and will it fit where I only have shallow space behind the surface?
Half an inch deep. The 56111 is 4 inches in diameter with a 1/2 inch depth, which is why it works where you have almost no cavity behind the finish surface, over furring, under a concrete deck, or on a surface where a full-depth box would never recess. That shallow depth is also the trade-off: you get 6 cubic inches to work in, so plan the splices accordingly.
2) Is the 56111 a stamped box or a one-piece drawn box, and does that matter for a damp or exposed location?
Drawn construction, formed from steel in one piece rather than assembled from folded sections. For an electrician that means no seams at the corners of the shell, which is the reason drawn boxes are preferred where the box is going to see mechanical abuse or get buried in a ceiling you do not want to open again. The material is steel throughout with a silver finish.
3) Should I use a 4-inch round box or a 4-inch square box for a ceiling fixture?
Round is the right pick when the thing you are mounting is round, a ceiling luminaire canopy, a smoke detector base, or a keyless lampholder, because the 4 inch diameter matches the canopy and there are no corners poking past it. Go square instead when you need volume for multiple cables or when you are mounting a device such as a switch or receptacle behind a plaster ring. The 56111 at 6 cubic inches and 1/2 inch deep is a fixture-outlet box, not a device box.
4) Do I order the Steel City 56111 by the box or by the piece?
Each. The 56111 is sold as a single box, so the count you enter is the number of boxes you need, not a carton multiple. Useful if you are picking up two for a punch list rather than a case for a rough-in.
5) What is the exact manufacturer part number for the Steel City 4-inch round drawn steel box?
Steel City 56111. It is the 4 inch round drawn steel box, 6 cubic inch, with 1/2 inch knockouts, made in Canada. If you are matching to a submittal or a distributor line item, 56111 is the number to quote.
