Steel City RS11-30 – Frequently Asked Questions
1) Will the Steel City RS11 cover fit a standard 4-inch square electrical box?
Yes. The RS11 is a 4-inch square raised device cover, so it mounts to any standard 4-square box using the box's two diagonal cover screws. Shape is square and nominal size is 4 inches.
2) How many receptacles does the Steel City RS11 4-square cover accept?
One. It's a single-device cover with a flush receptacle opening, so it takes one duplex receptacle on a 4-square box. If you need two devices on the same box, you need a two-gang raised cover instead.
3) Does a raised receptacle cover add box fill volume for conductor count?
Yes, and that's often why it gets specified. The RS11 raised device cover adds 5 cubic inches of volume to the box, which counts toward your box fill calculation along with the box's own cubic capacity.
4) Is the Steel City RS11 cover suitable for a damp or unfinished area like a garage or basement?
The RS11 is pre-galvanized steel, which gives it corrosion resistance for dry and typical unfinished interior locations such as garages, basements, and mechanical rooms. It is not a weatherproof or gasketed cover, so for wet or outdoor locations use a weatherproof cover and box instead.
5) What is the difference between the RS 11 and RS11-30 Steel City covers?
Both are the same 4-square single flush receptacle raised cover. RS 11 is the standard cover; RS11-30 is the raised surface device (RSD) version rated at 5 cubic inches. Order by the MPN that matches your box fill paperwork or spec.
6) Will a raised device cover work on a flush-mounted box behind drywall?
A raised device cover like the RS11 is intended for surface-mounted 4-square boxes, where the raise brings the device out to the finished face. For a box recessed in drywall you want a flat device ring sized to the wall thickness, not a raised surface cover.
7) Will the RS11 cover match the galvanized steel boxes already installed in my building?
It should. The cover is steel with a pre-galvanized finish in a silver appearance, which is the same look as standard galvanized 4-square boxes and raised covers, so it blends with existing surface-mounted runs.
8) Is the Steel City RS11 sold individually or in a carton?
Selling unit is each, so you can order the exact count you need for a job rather than a full carton.
9) Is the Steel City RS11 box cover made in the USA?
Yes, country of origin on the RS11 raised device cover is the United States, which matters if you are buying under domestic-sourcing requirements on a public project.
