No. The 18184 SCGV carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against rain, hose-down, dust ingress, or oil. For wet or outdoor locations you need a Type 3R, 4, or 4X enclosure instead.

It measures 18 inches high by 18 inches wide with a 4 inch depth, so it is a square box on the wall with a shallow back-to-front profile. That 4 inch depth is the number to check first if you are stacking terminal blocks, looping large conductors, or need bending room behind a cover.

Surface mounting through thru holes in the back of the enclosure, so you fasten it directly to the wall, strut, or backboard with your own anchors or machine screws. Mounting fasteners are not part of the enclosure. The cover also has keyhole slots, which lets you back the cover screws out part way and lift the cover off rather than fully removing every screw.

The enclosure is certified to UL 50, the standard covering enclosures for electrical equipment, and it is rated NEMA Type 1. Those are the two things an inspector will look for on an indoor pull or junction box.

Nine knockouts on each side, nine on the top, and nine on the bottom, so conduit can enter from any of the four edges without you having to punch the box in the field. The back is left clear for surface mounting.

It ships unfinished in galvanized steel, grey in appearance, with plated cover screws. There is no paint system on it, so it is meant for mechanical rooms, back-of-house, and utility spaces rather than finished occupied areas. If the box has to match a painted wall, plan on field painting or specify a painted enclosure.

No hinge. The SCGV is a screw cover enclosure, so the cover comes off entirely when you open it. The keyhole slots make that quicker, but if the box will be opened routinely for testing or resetting equipment, a hinged-cover enclosure is the better choice. Screw covers suit pull points, splices, and terminations you rarely revisit.

Order it as Eaton B-Line 18184 SCGV. The number reads as the dimensions plus the enclosure type: 18 inch height, 18 inch width, 4 inch depth, screw cover galvanized. It is manufactured in the US.

16 gauge galvanized steel walls. That is the usual body weight for a box this size and it keeps the sides from oil-canning when you tighten conduit connectors on a 9-knockout face.

15.7 lb empty. A single installer can hang it, though at 18 by 18 inches it is easier to set the top anchors first and let the box hang while you level and drive the rest.
