No. The 16126 SC NK carries a NEMA 1 rating, which is indoor, general-purpose enclosure protection only. It keeps fingers and falling dirt out of the wiring compartment but does nothing against rain, hose spray, or wet-location dust. For an exterior wall, a loading dock, or anywhere subject to washdown, step up to a NEMA 3R or NEMA 4 painted steel enclosure instead.

It is a 16 x 12 x 6 inch box: 16 inch height, 12 inch width, and 6 inch length/depth. The 6 inch depth is the number that usually decides the job, since it sets how much room you have behind the cover for splices, terminal blocks, or a small din rail once the conduits land on the sides.

The NK in the designation means no knockouts. The box ships as a blank carbon steel shell, so you drill or punch every conduit entry yourself exactly where your runs come in. That is the reason a lot of contractors prefer it for retrofit work, but it does mean bringing a hole punch or step bit to the job. If you want factory openings, order the knockout version of the screw cover box instead.

It is a surface mounted enclosure with thru holes in the back pan, so it fastens flat against a wall, a column, or a strut rack using your own anchors or bolts through those holes. No standoff feet or flush trim ring is part of it. It is not a flush or recessed box, so it is not for dropping into a drywall pocket.

The cover is a screw-on type held by plated screws, and it has keyhole slots so you can back the screws out partway, drop the cover onto the slots, and let it hang while you start the remaining fasteners. That is what makes it a one-person job on a 16 x 12 box. Screw covers are for enclosures you open rarely, terminations and pull points. If a technician needs regular access to devices inside, a hinged or clamped cover enclosure is the better choice.

The body is 16 gauge carbon steel and the box weighs 12.3 pounds empty. Size your anchors for that plus whatever conduit and conductors you land on it, since rigid runs entering the sides will add real load. Into masonry or concrete, standard sleeve or wedge anchors through the thru holes handle it; into stud wall, hit framing rather than relying on hollow-wall anchors.

It is built to UL 50, the standard covering enclosures for electrical equipment, and country of origin is the United States. That combination is what most institutional and government specs are looking for on a junction box submittal, alongside the NEMA 1 type designation.

A screw cover box like the 16126 SC NK is a wiring enclosure, a pull box, splice point, or terminal housing. It is a small single door style shell with no backplate, rails, or device provisions included, so if you are mounting a contactor, relay, or terminal strips you need to add a panel or mounting hardware. For anything an operator touches or a tech services regularly, look at a hinged cover control enclosure rather than a screw cover.

It is painted ANSI 61 grey, the standard light grey used across most industrial control and enclosure lines, so it reads as a match alongside typical panelboards, disconnects, and control enclosures in a facility. Painted carbon steel also means field touch-up is straightforward where the finish gets scratched during install.
