Steel City 52151 1/2 3/4 – Frequently Asked Questions
1) What size is the Steel City 52151 outlet box and how many cubic inches does it give me for conductor fill?
The Steel City 52151 is a 4 inch square steel box, 1-1/2 inches deep, with 21 cubic inches of capacity. That 21 cubic inch volume is what you work against when you count conductors, devices, clamps and grounds for box fill.
2) Can I use this Steel City 4 inch square box outdoors or in a wet location?
No. The 52151 is not weatherproof, so it is for dry, indoor locations only. For an exterior wall, a soffit, or anywhere exposed to weather, you need a listed weatherproof box and a gasketed in-use cover instead.
3) How does the 52151 4 inch square box mount, and does it come with a bracket?
It is a plain wall or ceiling mount box, fastened through the back to the stud, joist or surface. There is no bracket or bar hanger included, so if you need a nail-on stud bracket or an adjustable bar hanger for a joist bay, order that separately. Same for the cover: the 52151 is the box only, and you specify the flat, raised or plaster ring cover your device and wall finish call for.
4) Is the Steel City 52151 outlet box UL listed?
Yes. The 52151 carries UL file E2969 as its listing standard, which is what most inspectors and spec writers want to see on a steel outlet box in a commercial job.
5) How many devices does the 52151 outlet box support?
It is a single-gang arrangement, one outlet position. With a two-gang plaster ring a 4 square can carry two devices, but the box itself is configured and rated here for one. For a true two-gang rough-in, plan on the ring or a larger box.
6) How many boxes come in a case of Steel City 52151, and what do they weigh?
They ship 50 to the carton. Weight runs 62.5 lbs per 100 boxes, and the carton measures 20.625 x 8.25 x 8.187 inches. Useful numbers if you are staging material by floor or figuring a pallet.
