B-Line Eaton series Type 1 junction boxes, 24" height, 8" length, 24" width, 1, Screw cover, SC NK enclosure, Surface mounted, Medium single door, No

No. The 24248 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact with the enclosed equipment and falling dirt. It gives no protection against rain, hose-down, dust ingress or corrosive liquids. For a wet, outdoor or wash-down location you need a Type 3R, 4 or 4X enclosure instead. The painted carbon steel body is also not suited to damp environments.

It measures 24 inches high by 24 inches wide with an 8 inch depth, so the cover face is a 24 x 24 square and the box stands 8 inches off the wall. That depth matters when you are stacking terminal blocks or looping large conductors, and the 24 x 24 face gives you the mounting real estate for a medium single door style layout.

No knockouts. The NK in the model designation means no knockout, so the box ships with blank walls and you drill or punch your own conduit openings exactly where the run lands. That is the usual choice on a custom pull or splice box; if you want factory conduit entries you need a knockout version instead.

Surface mounted through thru holes in the back of the box, so it fastens flat to a wall or backboard with your own anchors or lags. It weighs 41.9 lb empty, so on drywall or block plan the anchors accordingly and expect two people to hold it while the first fasteners go in.

It can be. The 24248 SC NK uses a screw-on cover with plated screws and keyhole slots, so the cover lifts and drops onto partially backed-out screws rather than needing every screw pulled all the way out, which speeds up removal and refitting. Still, for a box you open weekly, a hinged door enclosure is the better call. A screw cover suits pull, splice and terminal boxes that get opened occasionally.

The body is 14 gauge carbon steel, which is the heavier end of what you see on junction and pull boxes and holds its shape when you are pulling large feeders through a 24 x 24 box. It is UL 50 listed as an enclosure for electrical equipment.

The box is painted in ANSI 61 grey, which is the standard grey used across most switchgear, panelboards and control enclosures, so it lines up visually with the rest of a typical electrical room. It does not need field painting.
