Steel City 52CADJ – Frequently Asked Questions
1) Does the 52CADJ adjustable mud ring fit a standard 4 inch square electrical box?
It does. The ring measures 4 inches by 4 inches, matching the face of a standard 4 inch square box, so it mounts on the box ears the same way a fixed mud ring does.
2) Why choose an adjustable mud ring instead of a fixed-depth raised cover?
A fixed raised cover only works if you know the exact finished wall thickness before the box is set, and it comes in set depths like 1/2 or 5/8 inch. The Steel City 52CADJ spans 1/2 to 1-1/2 inch in one part, so a rough-in crew can set boxes before the finish schedule is settled and the trim-out crew dials the ring flush later. On remodels, where existing wall thickness is anybody's guess until the board is open, that flexibility is the whole point. If every opening on the job is plain 1/2 inch drywall, a fixed ring is the simpler buy.
3) Is the Steel City 52CADJ mud ring made in the USA for Buy American jobs?
Country of origin is the United States, which is what government, school district, and federally funded projects usually need documented on electrical rough-in material.
4) Does the adjustable mud ring come with knockouts for running additional conduit?
No. The 52CADJ has zero knockouts, so it is a solid ring for bringing a device out to the finished wall surface, not a point for additional raceway entry. Any added conduit runs go into the box itself.
5) What is the Steel City 52CADJ mud ring made of, and will it hold up in a commercial install?
Steel, in a silver finish. Steel rings take the repeated device-screw torque and wall abuse of commercial and multi-family work better than plastic, and they keep the metallic bonding path continuous with a steel box.
6) Is the Steel City 52CADJ sold individually or by the box?
The selling unit of measure is each, so quantity counts are per ring. Order the piece count your opening schedule calls for rather than assuming a carton multiple.
