Steel City RS 12 – Frequently Asked Questions
1) Will the Steel City RS 12 cover fit a standard 4 inch square outlet box?
Yes. The RS 12 is a 4 inch square surface cover, so it mounts on the two diagonal screw holes of any standard 4 inch square (4SQ) box. It takes one duplex receptacle and raises 1/2 inch off the box face, adding 5 cubic inches of usable box volume for conductor fill calculations.
2) Does the 1/2 inch raised cover on a 4 square box add box fill volume I can count?
It does. The RS 12 contributes 5 cubic inches, which you add to the box's own cubic-inch capacity when running conductor fill. That extra volume is often what keeps a crowded 4 square box legal when you are landing a duplex plus pigtails.
3) Is this cover for one duplex receptacle or for a switch?
The RS 12 is cut for a single duplex receptacle, one device opening with the two mounting holes on the duplex pattern. A toggle switch will not fill the opening; for a switch on the same 4 square box you need a raised cover with a toggle cutout.
4) Is the RS 12 raised device cover OK for a damp or outdoor location?
No. Pre-galvanized steel like the RS 12 is intended for dry, interior surface work, exposed conduit in shops, basements, garages, mechanical rooms. For wet or damp locations you want a gasketed weatherproof cover with a cast or die-cast body and a weatherproof receptacle cover plate instead.
5) Do I need a separate wall plate over the RS 12 cover?
Yes. The raised cover holds the duplex receptacle but leaves the device face exposed, so you still finish it with a standard duplex wall plate. Order the cover by the each, model RS 12, and add the receptacle and plate separately, neither is included.
6) Is the Steel City RS 12 UL listed?
Yes, it carries UL file E2969.
7) Will this galvanized cover match the other surface boxes already in my building?
It should blend with existing pre-galvanized 4 square work. The finish is bare pre-galvanized steel with a silver appearance, the same unpainted look as standard 4 square boxes and conduit fittings, so replacing one cover on a run will not stand out.
8) Where is the Steel City RS 12 made?
The RS 12 raised device cover is made in the United States, which matters if you are filling a government or institutional order with domestic sourcing requirements.
