No. The 16166 HC NK is a NEMA Type 1 enclosure, which is for indoor use only, protecting personnel from live parts and keeping out falling dirt. It has no rating for rain, washdown, dust, or corrosive locations, so a wet or exterior wall needs a Type 3R or Type 4 box instead.

It measures 16 inches high by 16 inches wide with a 6 inch depth, so you need a 16 by 16 inch clear area on the wall and 6 inches of projection off the face. The steel weighs about 15 pounds bare, before any devices or wire go in.

No knockouts. The 16166 HC NK ships blank, so every conduit entry gets punched or hole-sawed on site where you want it. That is an advantage when your conduit runs do not line up with a factory pattern, but budget time for a knockout punch set and plan to debur and bond each opening.

Yes, the 16166 HC NK carries UL 50, the standard for enclosures for electrical equipment, and it is made in the US. That covers the enclosure itself as a Type 1 indoor box. If your drawing calls for a Type 12 or 4X, this one does not meet it.

Surface mount through holes in the back of the box. There are no mounting feet or flanges to work around, and no mounting hardware is supplied, so pick anchors or machine screws to suit the substrate, whether that's block, drywall with backing, or Unistrut.

Both, in effect. The cover is hinged so it swings open for service without a second pair of hands, and it is also removable if you want it off the box entirely during rough-in or wire pulling. A recessed pull ring and friction dimple hold it shut and let you open it without a tool.

Carbon steel at 16 gauge, painted ANSI 61 grey, which is the standard grey used across most industrial control enclosures so it blends with existing panels in a plant or mechanical room. Bare carbon steel is not corrosion resistant on its own, so keep the paint intact when you punch conduit holes.

At 6 inches deep with a 16 by 16 face, there is room for splice work, terminal strips, or a small subpanel of devices while still keeping bending space at the conduit entries. If you are landing large feeders where the conductor bending radius drives the box size, check your required wire bending space against the 6 inch depth before committing.

Go hinged when the box gets opened regularly, for terminations you troubleshoot, control wiring, or anything an inspector or tech revisits. A screw cover is fine for a pull box that gets closed once. The 16166 HC NK is a small single door style with a hinged, removable cover, so it serves both cases without you handling loose cover screws on a ladder.
