B-Line Eaton series Type 1 junction boxes, 48" height, 12" length, 48" width, 1, Screw cover, SCGV NK enclosure, Surface mounted, Medium double door,

No. It's a NEMA Type 1 enclosure, which means indoor use only, for protection against incidental contact and falling dirt. There's no gasket and no water or dust rating, so wet, damp, outdoor, or washdown locations call for a NEMA 3R, 4, or 4X box instead. Note also that the galvanized steel body is supplied unfinished, which is another reason it belongs in a dry indoor space.

48 inches high, 48 inches wide, and 12 inches deep. That 12 inch depth is what makes it usable as a wiring trough or gutter for large conductor bends and splices, and the 48 by 48 face gives a lot of room for terminal blocks or a mounted panel.

No knockouts. The SCGV NK box ships blank, so every conduit entry gets field punched or hole sawed where your run actually lands. That's the reason to choose NK over a knockout version: you keep the layout flexible, but budget time on the job for punching.

It's a screw cover, not a hinged door, so the cover is fully removable rather than swinging open. B-Line puts keyhole slots on the cover so you can back the plated screws out part way, lift the cover off the slots, and set it aside without chasing loose hardware. On a 48 by 48 cover, plan on two people or a good place to lay the cover down. The whole assembly weighs 219.8 lb, so the box itself is a rigging job.

219.8 lb, dead weight, before any conductors or devices go in it. This is a surface mount enclosure with thru holes in the back for lag or bolt fastening, so the mounting points need to land on structure, not just drywall or a single stud. On block or concrete use anchors rated well above that load; on stud framing, blocking or a unistrut subframe across studs is the usual approach.

It's built to UL 50, the standard covering enclosures for electrical equipment, and carries a NEMA Type 1 rating. That is the pairing an inspector expects for an indoor general purpose junction or pull box. It is also made in the US, which matters on Buy American funded work.

Screw cover suits a box you open rarely: a pull box, splice point, or wiring trough where the cover goes on once after the pull is dressed. It's cheaper to buy per square inch of access and there's no hinge to sag on a 48 by 48 face. If your crew or maintenance team needs to get into it regularly, or you're mounting devices inside that get adjusted, a hinged door enclosure is the better call. This one is the medium double door screw cover style in galvanized steel.

Eaton B-Line part number 484812 SCGV NK. Reading the number: 48 by 48 by 12 inches, SC for screw cover, GV for galvanized, NK for no knockouts. If you need a factory knockout pattern or a painted finish, that's a different suffix in the same family.
