No. The 24124 SC 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, dust, or oil. For an exterior wall, a loading dock, or a kitchen, you need a Type 3R, 4, or 4X box instead.

It measures 24 inches high, 12 inches wide, and 4 inches deep. That 4 inch depth is the number to watch if you are stacking terminal blocks or making up large conductors, since it sets your wire bending room behind the cover.

Knockouts are provided: 9 on the sides, 5 on the top, and 5 on the bottom. That is enough for most feed-and-branch junction work without pulling out a hole saw or a knockout punch, though the carbon steel 16 gauge body will accept a punched hole if you need conduit somewhere the factory knockouts do not land.

A screw cover box like the 24124 SC is the right call where the box is opened rarely, for splices, pull points, and terminations that get inspected occasionally. The cover comes off entirely with plated screws, so you need two hands and somewhere to set it down. If the enclosure holds controls or devices that get accessed regularly, a hinged door version is easier to live with. The keyhole slots in this cover do let you back the screws off part way and lift the cover clear rather than fully removing every fastener.

Surface mounting, using thru holes in the back of the box. You fasten straight through the rear panel into the wall or strut, so plan your anchors before you land conduit. Note that thru holes mean penetrations through the back wall of the enclosure, which is acceptable in a Type 1 indoor box but would compromise a sealed rating.

Order it as B-Line 24124 SC. The number reads directly off the dimensions: 24 inches high, 12 inches wide, 4 inches deep, with SC for screw cover.

Painted ANSI 61 grey, which is the standard grey used across most industrial control and junction enclosures. If your existing gear is ANSI 61, this will sit alongside it without looking like a patch job.

14.5 pounds empty. A single installer can set it, but with only thru-hole mounting and no keyhole hangers on the back, it is easier with a helper or a couple of pre-set anchors to hang it on while you start the fasteners.

Yes, country of origin is the United States. That matters on public and federally funded work where domestic sourcing is written into the spec.
