Steel City 58 C 30 – Frequently Asked Questions
1) Will the Steel City 58 C 30 cover fit a standard 4 x 2-1/8 handy box?
Yes. The 58 C 30 is sized 4 inches by 2-1/8 inches, which is the standard single-gang utility (handy) box footprint. It mounts to the box face with the two center screws in the box ears.
2) Is this utility box cover for a toggle switch or a receptacle?
Toggle switch. The 58 C 30 is punched for one standard toggle switch, so it will not accept a duplex receptacle or a decorator/GFCI device. For a receptacle on a handy box you need the duplex-punched version of the cover instead.
3) Will a pre-galvanized steel switch cover hold up in a damp basement or garage?
The 58 C 30 is steel with a pre-galvanized finish, which handles dry and normally damp interior locations like basements, garages, mechanical rooms and shops. Pre-galvanized is not the right choice for wet locations or direct weather exposure, where a gasketed weatherproof cover is required.
4) Does the 58 C 30 cover include the switch or the mounting screws?
The 58 C 30 is the cover only. The toggle switch is bought separately, and it mounts to the cover, which then fastens to the handy box using the box's own cover screws.
5) Does the Steel City 58 C 30 come as a single cover or in a pack?
It is sold each, so one cover per unit ordered. For a job with a run of surface-mounted switches, order the quantity of boxes you are covering.
6) What does the Steel City 58 C 30 look like once installed?
A flat rectangular silver steel plate over the face of the box, with a single toggle switch opening. Because it is pre-galvanized steel rather than painted, the finish is a plain mill silver, which matches standard EMT and steel boxes on exposed commercial and industrial work.
7) Is the Steel City 58 C 30 made in the USA?
Country of origin on the 58 C 30 utility box cover is the United States, which matters on public and federally funded work with domestic sourcing requirements.
