Steel City 3-GCS – Frequently Asked Questions

1) What size box does the Thomas & Betts 3-GCS cover fit?
The 3-GCS is sized for a standard 3-gang box and measures 8-13/16 by 4-11/16 inches. If your box is a 2-gang or 4-gang, this plate won't line up; match the gang count to the box before ordering.
2) Is the 3-GCS a flat blank cover or does it have device openings?
It's a flat, low-profile cover without raised device openings. Use it where you need to close out a 3-gang box; if you're finishing out switches or receptacles that need to come through the plate, you need a device cover with the matching cutouts instead.
3) Will a pre-galvanized steel box cover hold up in a damp or unheated space?
The 3-GCS is pre-galvanized steel, which gives it corrosion resistance for rugged job-site conditions such as unfinished basements, garages and mechanical rooms. For wet locations or direct weather exposure, a gasketed weatherproof cover is the correct choice, not a flat pre-galvanized plate.
4) What is the manufacturer part number for the Steel City 3-gang flat cover?
Order it as 3-GCS, part of the Steel City line from Thomas & Betts. That single part number covers the flat 3-gang steel cover; there are no finish or size options to specify.
5) Can I use the 3-GCS on both new construction and remodel work?
Yes. It's used for flush-mount 3-gang box closeout in both new construction and renovation wiring, residential or commercial. Property managers standardizing on one cover across a building can spec the same 3-GCS at every 3-gang location.
