B-Line Eaton series Type 1 junction boxes, 16" height, 6" length, 12" width, 1, Hinged cover, HC NK enclosure, Surface mounted, Small single door, No

It measures 16 inches high, 12 inches wide, and 6 inches deep. That 6 inch depth is what usually decides the job, since it sets how much room you have behind the cover for splices, terminal blocks, or a small DIN rail. Weight is 12.5 lb bare.

No. NEMA 1 is indoor only, for protection against incidental contact with enclosed equipment and falling dirt. It offers no rating against water, washdown, or dust. For an outdoor wall, a damp loading dock, or anywhere hosed down, you need a NEMA 3R, 4, or 4X enclosure instead. The 16126 HC NK belongs in dry indoor electrical rooms, ceilings, and interior corridors.

No knockouts. The NK in 16126 HC NK means no knockout, so the box ships blind and you punch or drill your own conduit entries wherever the run lands. Plan on a knockout punch set and the right connectors. If you want factory openings, order a knockout version of the box instead.

It is a surface mount enclosure with thru holes in the back pan, so you fasten it directly to the wall or structure through those holes. Fasteners are not part of the box, so supply anchors suited to your substrate (toggles or strap anchors in drywall, sleeve anchors in masonry, machine screws into Unistrut). At 12.5 lb empty plus conductors, anchor into structure rather than board alone.

The cover is hinged, so it swings open and stays with the box instead of coming off in your hand on a ladder. It also has a recessed pull ring and friction dimple to hold it shut, and the cover is removable if you need it fully off to work. A screw cover box is cheaper and lower profile but you handle loose screws and a loose plate every time you open it. For a box you expect to enter repeatedly, pick the hinged one.

The body is carbon steel at 16 gauge, painted in ANSI 61 grey. Sixteen gauge is the normal commercial weight for a box this size, stiff enough that the walls do not flex when you pull conduit into them or cantilever a device off the back pan. The painted finish suits dry indoor industrial and MRO spaces; for corrosive or wet areas, go to a stainless or nonmetallic enclosure.

Order it as B-Line 16126 HC NK. The paint is ANSI 61 grey, the same standard grey used across Eaton B-Line enclosures and most switchgear, so it lines up visually with existing panels and pull boxes in an electrical room. Style is a small single door enclosure.
