Steel City 52 C 18 – Frequently Asked Questions
1) Will a Steel City 2-gang raised ring fit a standard 4-inch square box?
Yes. The Steel City 52 C series raised ring is sized for a 4 inch square (4SQ) steel box, and it converts that single opening into a two-gang device opening for stacking two switches or receptacles. The ring mounts to the box ears with the box's own cover screws.
2) How much box fill does a 3/4 inch 2-gang raised ring add?
The 3/4 inch deep version adds 9 cubic inches of volume to the box, which counts toward your conductor fill calculation on top of the box's own cubic capacity.
3) Is this raised ring UL listed?
The Steel City 4-square 2-gang raised ring carries UL file E2969.
4) Can I use a Steel City pre-galvanized raised ring in a damp or outdoor location?
No. The 52 C ring is pre-galvanized steel, which is intended for dry indoor work such as stud walls, drop ceilings, and exposed indoor conduit runs. For wet or outdoor locations use a weatherproof cover and box assembly rated for that use instead.
5) Do I order these raised rings by the piece or by the box?
The 52 C 18 and 52 C 19 rings sell each, so you can buy the exact count a job needs rather than a full carton.
6) What finish will the ring be once the wall plate goes on?
Bare silver-toned galvanized steel. It sits behind the device plate, so the finish is not a visible detail on a completed opening, and it takes paint if the ring will be exposed on an open-ceiling install.
