No. The 121210 SCGV NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, hose-down, dust or oil. For an outdoor or wet location you need a Type 3R or Type 4 enclosure instead. Use this one in dry indoor spaces such as electrical rooms, back-of-house corridors and mechanical rooms.

It measures 12 inches high, 12 inches wide and 10 inches deep. The 10 inch depth is generous for a box this size, which is what makes it usable as a pull or splice point where you need bending room for larger conductors rather than just a small device box.

No knockouts. The NK in 121210 SCGV NK means no knockout, so every conduit entry gets punched or drilled where you want it. That is an advantage when your conduit runs do not line up with a standard knockout pattern, but budget time for a hole saw or knockout punch and plan on your own connectors and sealing washers. If you want pre-punched entries, order a knockout version instead.

It is a surface mount box with thru holes in the back pan, so it fastens flat to a wall, backboard or strut with your own fasteners sized to the substrate. Mounting screws, anchors and conduit connectors are not part of the box. At 13.1 pounds empty, anchor into studs, masonry or Unistrut rather than drywall alone.

It carries UL 50, the standard for enclosures for electrical equipment, and it is built to NEMA Type 1. If your submittal calls for a UL 50 Type 1 screw cover enclosure, this meets that line. It is made in the US, which matters on projects with domestic sourcing requirements.

It is a screw cover, not a hinged door, so the plated screws come all the way out to remove the cover. The cover has keyhole slots, so once the screws are backed off part way you can lift and slide the cover free without fully removing every screw, and reseat it the same way. That saves time on a box you open regularly, but it still needs both hands and clear space in front of it, unlike a hinged enclosure.

It is unfinished galvanized steel, grey in appearance, with no paint coat. The zinc coating gives reasonable resistance to incidental moisture and condensation typical of an indoor mechanical room, but it is still a Type 1 indoor enclosure and it is not intended for corrosive atmospheres or wet locations. If you need a painted finish to match other gear, this is not the box.

The body is 16 gauge galvanized steel. That is standard commercial weight for a box this size and stiff enough to carry conduit runs and terminal blocks without oil canning, which is why it shows up in MRO and institutional specs for pull and splice boxes.

The manufacturer part number is 121210 SCGV NK from Eaton's B-Line series. The number reads as the dimensions first (12 high, 12 wide, 10 deep), then SCGV for screw cover galvanized, then NK for no knockout. If you are standardizing a building on one box style, that naming pattern makes it easy to order matching sizes in the same cover and finish.
