Steel City 52 C 0 – Frequently Asked Questions
1) What is the Steel City 52 C 0 used for on a 4-inch square box?
The Steel City 52 C 0 is a flat single-gang mud ring (raised cover) for a 4 inch square outlet box. It closes off the square box and reduces the opening to one gang so a single device, a switch or receptacle, can be mounted. Flat means no raise, so it sits level with the box face rather than extending out into the wall material.
2) Will this ring fit any brand of 4-inch square box?
It is built to the standard 4 inch square box pattern, so it lands on the corner screw bosses of a conventional 4 square box regardless of who made it. The one thing to confirm is depth intent: this is the flat version, so it adds no raise over the box face.
3) Does the Steel City 52 C 0 ring have any knockouts in it?
No knockouts. The 52 C 0 is a solid flat plate with only the single-gang device opening, so there is no provision for bringing a cable or fitting through the ring itself. All conduit or cable entries have to come through the knockouts in the 4 square box behind it.
4) Is this ring galvanized well enough for a damp or unfinished area like a garage or warehouse?
The 52 C 0 is steel with a pre-galvanized finish, which is the normal specification for interior and dry commercial work, including unfinished spaces such as warehouses, garages, and mechanical rooms. Pre-galvanized is not the same as hot-dip for wet or outdoor locations, where you would specify weatherproof covers and boxes instead.
5) Do I need one of these rings for every 4-square box, or can I use a blank cover?
You need a device ring only where a switch or receptacle is going in. The 52 C 0 is the one-gang version, so it takes a single device. Where the box is a junction with no device, a flat blank square cover is what you want instead, and where two devices land in the same box you need a two-gang ring rather than this one.
6) How is the Steel City 52 C 0 sold, individually or by the box?
It sells each, so you can order the exact count for the job rather than a fixed carton. It is made in the United States.
