Steel City 54 C 6 – Frequently Asked Questions

1) Will a Steel City 4 inch octagon box cover fit a standard 4 inch round box too?
The Steel City 54 C 6 is an octagonal cover sized for 4 inch boxes, and 4 inch octagon and 4 inch round boxes share the same two-screw ear spacing, so it mounts on either. It will not fit a 4 inch square (1900) box, which needs a square cover.
2) Does this Steel City flat cover have a knockout for a fixture stem or wire pass-through?
Yes, it carries a single 1/2 inch knockout in the center, which is what you use to pass a fixture stem, nipple or cable connector through a blank flat cover. If you need a sealed blank with no opening, this is not the one.
3) I need to hang a ceiling fixture off an octagon box, is a flat 1/2-KO cover the right choice?
A flat cover with a 1/2 inch knockout works where the fixture canopy or stem passes straight through and the weight is carried by the box or a fixture stud. If you need the cover itself to let you adjust or swivel the fixture, a swivel-type cover like the RACO 894KH KWIK-HANG 4 in. round swivel cover for octagon boxes is the different tool for that job.
4) What is the difference between the Steel City 54C6 octagon box cover and the RACO 894KH round cover?
The Steel City 54C6 is a flat 4 inch octagonal steel box cover with a 1/2 inch knockout for bringing a fixture wire or stem through the center. The RACO 894KH is a 4 inch round swivel cover for octagon boxes in the KWIK-HANG series, so it is built to let a fixture be hung and rotated rather than sitting flat and fixed. If you are blanking off or landing a simple fixture stem on a 4 inch octagon box, the 54C6 suits; if you need a swivel-mount fixture support, the 894KH is the one shaped for it.
5) Is this cover suitable for a damp or unfinished area like a garage or crawlspace?
The cover is pre-galvanized steel, which gives it corrosion resistance for dry and typical indoor unfinished locations. It is a flat blank cover, not a gasketed weatherproof cover, so it is not a wet-location closure on its own.
6) Which 4 inch octagon cover should I standardize on for ceiling fixture replacements across a building?
For plain lighting outlets where a fixture stem or wire passes through the center, the Steel City 54C6 flat 4 inch octagon cover in pre-galvanized steel is the simpler item to stock, and it carries UL E2969. Keep a smaller quantity of the RACO 894KH 4 in. round swivel cover for octagon boxes for the locations where the fixture has to swivel or hang off the cover, since the flat cover does not provide that function.
7) Will this match the other octagon box covers already installed in my building?
Finish is silver, unpainted pre-galvanized steel, which is the standard look for exposed octagon box covers in utility and commercial spaces. If your existing covers are painted or a specific color-coded finish, this one will read as bare galvanized metal next to them.
