No. The 15156 SCGV NK is a NEMA Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It offers no rating against rain, washdown, dust, or oil. For an outdoor wall or a wet mechanical room you need a Type 3R, 4, or 4X box instead.

It measures 15 inches high by 15 inches wide with a 6 inch depth, so you get a square 15 x 15 opening behind a screw cover and 6 inches of gutter space for conductors, splices, or a small terminal block. Weight is 13.8 lb, light enough for one person to hold while driving the first fastener.

The 15156 SCGV NK is a no-knockout box. Every conduit entry has to be punched in the field, which is why electricians use the NK version when the conduit layout is not fixed at the time of order. Plan for a knockout punch or step bit sized to your fittings through 16 gauge steel. If you would rather have factory openings, order the knockout version of the same screw cover box instead.

Surface mount. The box back has thru holes for fasteners, so it bolts or screws flat to a wall, a strut backing, or a plywood backboard. There is no flush or recessed trim provision, and no mounting hardware is described as supplied, so pick anchors to suit your substrate.

A screw cover box like the 15156 SCGV NK has a flat cover fastened with plated screws, meant for a pull point or splice you open rarely. The cover carries keyhole slots so it hangs on partially backed out screws while you line up the rest, which matters when you are working overhead alone. If you will be opening the box regularly for service or it houses devices you monitor, choose a hinged door enclosure instead.

It ships unfinished in galvanized steel, grey in appearance, with plated cover screws. The zinc coating gives it reasonable resistance in dry indoor areas like electrical rooms, garages, and back-of-house corridors, but as a Type 1 box it is not intended for damp or corrosive environments. It can be painted in the field if you need it to match a finished wall.

The 15156 SCGV NK carries UL 50, the standard for enclosures for electrical equipment, and is rated NEMA Type 1. It is also made in the US. That is the documentation an inspector or spec reviewer normally wants for an indoor surface mounted pull box.

Yes for typical indoor branch circuit work. The 15156 SCGV NK body is 16 gauge galvanized steel, which is the usual wall thickness for screw cover junction boxes in this size and stiff enough to support punched conduit hubs and locknuts without oil canning. Support the conduit independently where runs are long or heavy.
