Steel City 541711/2-25 – Frequently Asked Questions
1) What size is the Steel City 541711/2-25 octagon box, and how many conductors will it hold?
It's a 4 inch diameter octagon box, 2-1/8 inches deep, with 22.5 cubic inches of volume. That cubic capacity is the number you use for conductor fill calculations, so size your box fill against 22.5 cu in rather than guessing from the diameter.
2) Can I use this Steel City octagon box outdoors or in a wet location?
No. The 541711/2-25 is not weatherproof. It's a drawn steel box for dry interior wall and ceiling mounting. For an exterior fixture or a damp/wet location you need a gasketed weatherproof cast or die-cast box with threaded hubs instead.
3) Is a 4 inch octagon box the right choice for mounting a ceiling light fixture?
Octagon boxes like the Steel City 541711/2-25 are the standard choice for ceiling outlets and luminaire mounting, and it's classified under the UNSPSC code for ceiling box. Use a square 4-11/16 box when you need more volume for pass-through conductors, and a fan-rated box if the outlet is supporting a paddle fan rather than a light.
4) Will a 2-1/8 inch deep octagon box fit in a 2x4 stud wall?
Yes. At 53.975 mm (2-1/8 inches) deep, the 541711/2-25 fits inside a nominal 2x4 stud bay, which gives 3-1/2 inches of depth. The 4 inch diameter is the dimension to watch, not the depth, since the box face has to clear the stud edges on a flat mount.
5) What material and finish is the Steel City 541711/2-25?
Drawn steel with a silver (galvanized-look) finish. Drawn construction means the body is formed from one piece with no seams at the corners, which matters when you want a clean, rigid box for a ceiling outlet.
