No. The 10106 SC NK carries a NEMA Type 1 rating, which is indoor, general purpose only: it guards against incidental contact with the enclosed equipment and falling dirt, with no protection against water, washdown, or dust ingress. For a damp or outdoor location you need a NEMA 3R or 4 enclosure instead. Indoors on a dry mechanical room, electrical room, or back-of-house wall is where this one belongs.

It measures 10 inches high, 10 inches wide, and 6 inches deep. That 6 inch depth is the number worth checking first, since it drives how much wall projection you get on a surface mount and how much room you have for wire bending and splices behind the cover.

No knockouts. The 10106 SC NK is supplied blank, so every conduit entry gets punched or drilled on site exactly where your runs land. That is the point of an NK box on a retrofit, but it means you need a hole punch set and the right connectors on the truck. If you would rather not field-punch, order a box with factory knockouts.

It mounts on the surface using thru holes in the back of the enclosure, so you fasten straight through the box into the wall or strut with your own anchors sized for the substrate. Anchors and screws are not part of the enclosure. At 7.7 pounds empty, two fasteners into masonry or into studs handle it fine, but drywall alone will not.

Not really. A screw cover means every entry costs you the time to back out and reinstall the cover screws, which is fine for a splice or pull box you open once a year. If a tech is in the box weekly, a hinged or clamped cover enclosure saves labor. What the screw cover does buy you is a flatter, tamper-discouraging closure and fewer parts to fail, and the cover here has keyhole slots so it hangs on the screws while you line it up, plus plated screws that do not seize up like bare steel.

Carbon steel at 16 gauge, painted in ANSI 61 grey. Sixteen gauge is the usual commercial weight for a box this size, so it takes conduit, connectors, and a field-punched hole without oil-canning. ANSI 61 grey is the standard industrial control gear color, so it matches panels and starters already on the wall in most plant and mechanical rooms.

It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. That combination is what most institutional and government specs are looking for when they call out a domestic, UL 50 Type 1 enclosure on a submittal.

Yes, within its 10 x 10 x 6 inch interior. It is a blank single-door steel box with a removable screw cover, so it works as a splice point, pull point, or small terminal box wherever a Type 1 indoor enclosure is acceptable. Size your conduit entries and pull space off the largest raceway you are landing in it, since the 6 inch depth sets what bending room you actually have.
