Steel City 72 C 3 – Frequently Asked Questions
1) Does a raised box cover add to the box fill volume?
It does. The 72 C 3 raised cover adds 3.5 cubic inches of usable volume, which counts toward your box fill calculation on top of the box's own capacity. That extra 3.5 in3 is often what gets a crowded 4-11/16 box legal.
2) Does this Steel City cover come with knockouts for conduit or a device opening?
No knockouts. The 72 C 3 is a blank raised cover, so there are no pre-punched openings for conduit or a device. If you need to mount a receptacle or switch at the cover, order a device-specific raised cover rather than this blank.
3) How deep is the raise on the Steel City 72 C 3 cover?
It is a 5/8 inch raised cover. That raise is what gains you the extra 3.5 cubic inches of wiring space and lets the cover sit proud of the box face, which matters when the box is set behind drywall or a furring layer.
4) Is this box cover UL listed?
Yes, the 72 C 3 carries UL file E2969.
5) Is the 72 C 3 cover steel or plastic, and will it hold up in a damp mechanical room?
Steel, with a pre-galvanized finish and a silver appearance. The zinc coating gives it reasonable corrosion resistance for indoor industrial and mechanical spaces. For wet or outdoor locations you want a gasketed weatherproof cover instead, since this one is not described as weatherproof.
6) Is the Steel City 72 C 3 sold individually or by the carton?
The selling unit is each, so you can buy a single cover rather than a full carton. Handy when you are closing out a punch list and only need a few.
