No. The 12104 SCGV NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, splashing water, or hose-down. For a wet location or an exterior wall you need a Type 3R or Type 4 box instead. Keep this one to dry indoor spaces, mechanical rooms, back-of-house corridors, and electrical closets.

It measures 12 inches high, 10 inches wide, and 6 inches deep. That 6 inch depth is what matters most on a retrofit: it gives you room for wire bending space and terminal blocks behind the cover, but it also means the box stands 6 inches proud of a finished wall since it is surface mounted.

No. The NK in 12104 SCGV NK means no knockouts. The body comes blank so you punch your own conduit entries exactly where the run lands. Plan on a knockout punch set or hole saw and appropriate connectors as part of the job; if you want factory knockouts, you need a different B-Line screw cover box without the NK suffix.

Yes, it carries UL 50, the standard for enclosures for electrical equipment, and it is made in the United States. Between the UL 50 listing and the NEMA Type 1 designation it will satisfy a typical indoor junction box callout on a commercial drawing.

The cover is a screw cover with plated screws, and it has keyhole slots so you can back the screws off partway and lift the cover clear without removing them completely. That is handy on a ladder. It is not a hinged door, so for an enclosure you open daily a hinged cover box is the better pick.

Through holes in the back of the box, for surface mounting. You supply the fasteners suited to the substrate, toggles or anchors in drywall or block, screws into studs or Unistrut. Nothing is included for mounting, and the box is not designed to be recessed into a wall cavity.

The body is galvanized steel, supplied unfinished in grey rather than painted. The zinc coating gives it better corrosion resistance than a bare or painted steel box in a humid indoor space, but it is still a Type 1 enclosure, not rated against dripping or sprayed water.

For a pull or splice point that gets opened rarely, the screw cover style like the 12104 SCGV NK is the normal choice, and the keyhole slots in the cover make the occasional opening quick. Choose a hinged door enclosure instead when you are mounting devices, breakers, or terminal strips that get worked on regularly, or where a loose cover on a ladder is a hazard.

16 gauge steel throughout, with a shipping and install weight of 7.3 pounds. At that weight two anchors rated for the substrate will carry it, but add the weight of conduit and conductors landing on it when you pick fasteners. The 16 gauge body also takes a knockout punch cleanly.
