No. The 181810 SCGV NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It is not sealed against water, so keep it out of the weather, off exterior walls, and away from hose-down or wash-down areas. For those locations you need a NEMA 3R, 4 or 4X enclosure instead.

It measures 18 inches high, 18 inches wide and 10 inches deep, so it's a square face with a deep back box, giving room for splices, terminal blocks or a small DIN rail assembly rather than just pull-through conductors. Plan 18 x 18 of clear wall area plus 10 inches of standoff from the finished wall surface.

It ships with no knockouts. The NK in 181810 SCGV NK means the box is blank on all sides, so you punch your own openings where your conduit runs actually land. That's the reason electricians pick the NK version, but it does mean you need a knockout punch or hole saw on site. If you want factory openings, order a knockout version instead.

The cover is a screw-on type with plated screws and keyhole slots, so you can back the screws out part way, lift the cover onto the slots and let it hang while you make up connections. The box itself weighs 22.8 pounds, which is a one-person lift but worth anchoring into studs or solid masonry rather than hollow drywall anchors.

The 181810 SCGV NK is a surface mount enclosure with thru holes in the back pan. You run your own bolts or lag screws through those holes into the structure, so pick fasteners to suit the substrate (wood studs, unistrut, block). The thru holes penetrate the back wall, so the box is not sealed at those points, which is fine for a Type 1 indoor location.

It is built to UL 50, the standard covering enclosures for electrical equipment. Paired with the Type 1 rating, that's what an inspector looks for on an indoor surface mounted pull or junction box. It is manufactured in the US.

A screw cover box such as the 181810 SCGV NK suits splices, pull points and terminal blocks you rarely open. The full cover comes off and gives unobstructed access to all four corners, which is easier for pulling conductors. If the box will be opened routinely for testing or holds devices someone adjusts, a hinged cover enclosure is the better pick because you are not handling loose screws on a ladder.

The Eaton B-Line part number is 181810 SCGV NK. The number reads as the dimensions first (18 high, 18 wide, 10 deep), then SCGV for screw cover galvanized, then NK for no knockouts.

The body is 16 gauge galvanized steel supplied unfinished, grey in appearance. There is no paint or powder coat on it, so if the box lands in a visible finished area you can prime it with a galvanized-compatible etch primer and top coat it. For utility rooms and above-ceiling work most crews leave it bare.

16 gauge steel on a box this size keeps the back pan rigid enough to carry mounted terminal blocks, small relays or a DIN rail without flexing, and it stands up to conduit torque when you tighten locknuts on punched openings. It also means punching your own holes needs a proper knockout punch rather than a light-duty hole cutter.
