No. The 12104 SCGV carries a NEMA 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It gives no protection against water, rain, hose-down, dust ingress, or oil. For a wet or wash-down location you need a NEMA 3R, 4, or 4X enclosure instead. Keep this one in dry indoor spaces: electrical rooms, mechanical rooms, above ceilings, interior wall surfaces.

It measures 12 inches high, 10 inches wide, and 4 inches deep. The 4 inch depth is what usually decides the job, it sets how much room you have for conductor bending space and splice devices behind the cover.

Knockouts are factory provided: 5 on each side, 5 on the top, and 5 on the bottom. Thru holes are also provided for mounting. If your conduit run does not line up with a knockout you can still punch the 16 gauge galvanized steel body, but for most side-to-side or top-and-bottom pass-through runs the existing knockouts will cover it.

It is a surface mount box with thru holes in the back for fastening straight to a wall, panel, or strut. At 7.2 pounds empty it is a one-person hang. The cover also has keyhole slots, so you can back the plated screws out part way and lift the cover off without chasing loose hardware on the floor.

A screw cover box such as the 12104 SCGV is the right choice where you open it rarely, at pull points, splice points, and junctions. The cover comes fully off, which gives you unobstructed access to all four sides for pulling wire. If the box is somewhere you will be opening routinely for testing or maintenance, a hinged door enclosure is easier to live with because the cover stays attached.

The 12104 SCGV is built to UL 50, the standard covering enclosures for electrical equipment. That plus the NEMA 1 designation is what an inspector looks for on an indoor junction or pull box in commercial and institutional work.

Order it as Eaton B-Line 12104 SCGV, from the SCGV screw cover galvanized series. Country of origin is the US.

The body and cover are 16 gauge galvanized steel, which is the usual weight for indoor pull and junction boxes and stands up to normal traffic and incidental bumps. What limits it in a garage is not the gauge, it is the NEMA 1 rating: open to weather, vehicle spray, or hose-down cleaning calls for a NEMA 3R or 4 enclosure rather than this one.

It ships unfinished, grey galvanized steel, with no paint topcoat. The zinc coating handles ordinary dry indoor conditions and cut or punched edges can be touched up with a cold galvanizing compound. If you need a specific color to match a panel schedule or an architectural spec, this box is not it, you would want a painted enclosure.
