No. The 12106 HC is a NEMA Type 1 enclosure, which is for indoor use only, protecting against incidental contact and falling dirt. It gives no protection against rain, hose-down, or dust ingress. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead.

It measures 12 inches high, 10 inches wide, and 6 inches deep. That 6 inch depth is what gives you room to land conduit fittings and make up wire inside without crowding the hinged door.

Yes. The 12106 HC has 5 top knockouts, 5 bottom knockouts, and 5 side knockouts, so you can bring conduit in from multiple directions without drilling the carbon steel shell. Thru holes are provided in the back for surface mounting.

Go hinged. The 12106 HC uses a hinged door, so the cover stays with the box when you open it, which matters on a service box you get into regularly for terminations or testing. It also has a recessed pull ring and friction dimple to hold it shut, and the cover is removable if you need it out of the way during rough-in. A screw cover box is the cheaper choice only if the box gets closed once and forgotten.

It is a surface mount enclosure with thru holes in the back for fasteners to wall, strut, or backboard. At 8.9 lb empty, one electrician can hold and set it, though a helper or a pair of temporary screws makes lining up the holes easier. Anchors and screws are selected for your substrate and are not part of the box.

The body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard grey used across industrial electrical gear, so it blends with panels and gutters already on the wall in a plant or mechanical room.
