No. The 16166 SC carries a NEMA 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It gives no protection against water, rain, hose-down, or dust. For a loading dock, rooftop, kitchen, or any damp location you need a NEMA 3R, 4, or 4X enclosure instead. Indoors, in an electrical room, plant ceiling, or corridor, it's the right class of box.

It's a 16 x 16 x 6 inch box: 16 inch height, 16 inch width, and 6 inch depth. That 6 inch depth is what gives you room to make up splices and bend radius behind a device, and it's the number to check against your wall cavity or the clearance in front of the mounting surface. Ordered weight is 15.2 lb.

Knockouts are factory provided: 7 on each side, 9 on the top, and 9 on the bottom. For most branch-circuit and control wiring pulls you won't need to punch anything. If your conduit run doesn't line up with a provided knockout, you'd punch the carbon steel shell yourself, but plan the layout around the existing pattern first since every punched hole in a NEMA 1 box still needs a proper connector or closure plug.

It's a surface-mount enclosure with thru holes in the back pan, so you fasten it straight through the box into the wall, strut, or backboard. The anchors or bolts are selected to suit your substrate and are not part of the enclosure. At 15.2 lb empty, plus whatever devices and conduit you land on it, fasten into studs, masonry anchors, or Unistrut rather than drywall alone.

It's built to UL 50, the standard for enclosures for electrical equipment, and carries a NEMA Type 1 rating. That's the pairing an inspector looks for on an indoor general-purpose junction or pull box. Made in the US.

The 16166 SC uses a screw-on cover, which suits a pull point or splice box you open only during service work. Plated screws and keyhole slots on the cover mean you can back the screws out part way and lift the cover off the slots rather than removing them completely and losing them in the ceiling. If your application means opening the box routinely, for instance a control or terminal enclosure an operator accesses, a hinged-door enclosure is the better choice.

Body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard grey used across most industrial electrical gear, so it matches adjacent panels and disconnects on a plant wall. Being painted carbon steel rather than stainless, keep it out of damp or corrosive locations where the paint film is the only thing between the steel and moisture.
