Steel City RSL 9 4-11/16 SQ SURF CVR, TOGGLE

Yes. The RSL 9 is a 4-11/16 inch square surface cover, so it mounts to a standard 4-11/16 square outlet box. It will not fit a 4 inch square box, which uses a smaller cover. If you have a 4 inch square box instead, you need a 4 inch square cover such as the RACO 897KH swivel cover.

It is punched for a single toggle switch. The RSL 9 is a 4-11/16 square surface cover with a raised toggle opening, so a standard single-pole or three-way toggle device mounts directly to it. It does not take a duplex receptacle or a decorator/rocker device.

7.5 cubic inches. That counts toward your box fill calculation on top of the volume of the box itself, which matters when you are crowding a 4-11/16 square with multiple circuits and a switch.

The RSL 9 is pre-galvanized steel, which gives it corrosion resistance suited to dry and normally damp indoor locations like basements, garages, and utility rooms. It is not a gasketed weatherproof cover, so for wet or outdoor locations use a listed weatherproof cover and box instead.

Two different jobs. The Steel City RSL 9 is a raised device cover: it closes the box and holds a toggle switch, adding 7.5 cubic inches of usable volume. A swivel cover like the RACO 897KH KWIK-HANG, made for 1/2 or 3/4 inch pipe, is for hanging or supporting the box from conduit, not for mounting a switch. Pick the raised toggle cover when you are finishing out a switch point; pick the swivel type when you are suspending a box.

Sold each, as the cover only. No toggle switch is included, so order the device separately. Appearance is a silver, unpainted galvanized steel finish typical of exposed-conduit work in mechanical rooms and commercial back-of-house areas.

Country of origin is the United States, which is what government, education, and healthcare procurement teams need confirmed when a job carries domestic-content language. The part number to specify is RSL 9.
