Steel City 2G 1/2 3/4 Gang Boxes

The box has 45 cubic inches of volume, which is what you size your conductor fill against under the box fill rules. That is a large-capacity two-gang steel box, so it handles crowded multi-wire runs, device grounds and pigtails that a standard shallow two-gang will not. Work the fill from the 45 cubic inches and the conductor sizes actually landing in the box.

It is a surface mounted steel housing, mounted horizontally. So it lands on the face of a wall, deck or structure rather than being set between studs behind drywall. If you need a flush device box in a finished wall, this is the wrong style of box.

The 2G 1/2 3/4 designation refers to combination 1/2 and 3/4 inch knockouts, and the box carries 17 of them. That gives you plenty of entry points to bring in EMT or connectors on more than one side without having to reposition the box to line up a run.

Box size is 4-1/2 inches length by 6-13/16 inches width by 1-5/8 inches depth, with a stated device width of 173.038mm. Because it mounts on the surface, the 1-5/8 inch depth is what projects off the wall plus whatever cover you add, so check that against any door swing, equipment clearance or walkway next to it.

Yes. It is configured for 2 outlets, so it takes a two-gang device arrangement, two receptacles, two switches, or a switch and receptacle combination, under a two-gang cover. It is set for horizontal mounting.

It ships in an outer quantity of 5 boxes. Shipping weight runs 112 lbs. per 100 boxes, which is useful if you are pricing freight on a large rough-in order.

Steel construction in a silver finish, not transparent. It is a standard unpainted-look metallic box, so if the install is in a finished space where appearance matters you will want a cover and, if required, field paint to match.

It classifies under UNSPSC 39121308, outlet box. That is the code to drop into a requisition or a government or institutional purchasing system when standardizing outlet box line items.
