No. The 12126 HC NK carries a NEMA 1 rating, which is indoor, dry-location only. It gives protection against incidental contact and falling dirt, not water, dust, oil, or corrosive atmospheres. For outdoor, damp, or wash-down locations you need a NEMA 3R, 4, or 4X enclosure instead.

12 inches high, 12 inches wide, and 6 inches deep. That 6 inch depth is what matters most for wire bending space and for terminal blocks or small DIN rail mounted parts, and the 12 x 12 face gives you room to land several conduit runs on the sides.

No knockouts. The 12126 HC NK is a blank box, so every conduit entry gets punched or drilled on site where you want it. That is an advantage when your raceway layout does not match a factory hole pattern, but budget time for a hole saw or a knockout punch set. It does come with thru holes for mounting.

Both. The cover is hinged so it swings open and stays with the box during service, and it is also removable if you want it out of the way while pulling wire or mounting components. A recessed pull ring and friction dimple hold it shut without separate latch hardware or a key.

It is a surface mount box with thru holes in the back pan, so it bolts flat to a wall, unistrut, or a backboard. The finish is painted ANSI 61 gray, the standard light gray used across most industrial control and distribution gear, so it will sit consistently alongside existing panels.

Body and cover are 16 gauge carbon steel, painted. That is the normal weight for a NEMA 1 screw-cover or hinged-cover box this size and it will carry terminal strips, relays, or a small contactor mounted to the back pan. The box itself weighs 10.1 lb empty, so one person can set it, though two hands help when you are lining up anchors.

Go hinged. On a screw cover you handle and re-thread every screw each time you open it, and the cover has to be held or set down. The 12126 HC NK swings open on its hinge and holds shut with a recessed pull ring and friction dimple, which is what you want at a splice or pull point that gets revisited. Screw cover is the cheaper choice for a box you close once and leave.

The catalog number is 12126 HC NK. The number reads out as the dimensions plus the options: 12 x 12 x 6 inches, HC for hinged cover, NK for no knockouts. It is part of the Eaton B-Line series Type 1 junction box line.
