No. The 1284 HC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It has no gasket and no water or dust seal, so wet locations, outdoor walls, washdown kitchens, and dusty process areas all call for a higher rated enclosure. Keep this one in dry indoor electrical rooms, corridors, and mechanical spaces.

It measures 12 inches high, 8 inches wide, and 4 inches deep. That 4 inch depth is what matters most on a wall run, since it sets how much room you have behind the hinged cover for splices, wire fill, and bending space. Plan your conduit entries around a 12 x 8 face.

No knockouts. The HC NK model is supplied blank, so the electrician drills or punches every conduit entry exactly where the run needs it. That is the point of the NK version: no unused openings to plug, and full freedom on hole placement. Budget for a hole saw or knockout punch set on the install.

It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. For a spec that calls out a UL 50 Type 1 painted steel pull or junction box, the 1284 HC NK answers it. Submittal reviewers on healthcare, education, and government work usually want both the standard and the country of origin, and both are on record here.

Surface mounting through holes in the back of the box, so it fastens flat to a wall, a strut rack, or a backboard with your own anchors or screws. It is not a flush or recessed box. At 6.3 pounds empty, standard toggles or tapcons into masonry or a plywood backboard will carry it fine. Fasteners are not part of the box.

Both, in effect. The 1284 HC NK uses a hinged cover that is also removable, so you can swing it open for routine access or take it right off when you need to work with two hands inside the box. It has a recessed pull ring and a friction dimple to hold it shut, which suits a box that gets opened often for splice checks or troubleshooting.

16 gauge carbon steel, finished in ANSI 61 grey paint. That is the standard grey used across most commercial electrical gear, so it blends with panelboards and control enclosures in the same room. Painted steel means indoor dry locations only, matching its Type 1 rating.

Pick hinged when the box gets opened more than once. A screw cover means handling four to eight screws every visit and eventually losing some; the hinged cover on the 1284 HC NK swings open with a recessed pull ring and stays put on a friction dimple. For a pull box that only gets opened during rough-in and never again, a screw cover is fine and cheaper. For splice boxes feeding controls, lighting relays, or anything you troubleshoot, hinged pays for itself.

Order it as B-Line 1284 HC NK. Reading the number: 12 x 8 x 4 inches, HC for hinged cover, NK for no knockouts. B-Line sizing runs height x width x depth, so a 1284 and a 1248 are not the same box. Distributors cross-referencing should match all three elements, since the same 12 x 8 x 4 body exists with screw covers and with knockouts.
