No. The 241812 SC is a NEMA Type 1 enclosure, which is indoor-only protection against dust and incidental contact. It has no gasket and the cover is held by screws, so rain, hose-down, or oil-laden air will get in. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead.

It measures 24 inches high, 18 inches long/deep and 12 inches wide. The model designation follows those numbers: 24-18-12, SC for screw cover. Plan your wall space and gutter fill around the 24 x 18 footprint before you lay out conduit.

Knockouts are provided on all four working faces: 9 on each side, 9 on top and 9 on the bottom. That gives you conduit entry without pulling out a hole saw for most layouts. If you need an entry where there is no knockout, the 16 gauge carbon steel body can be drilled or punched in the field.

Surface mount, using thru holes in the back of the enclosure. You anchor straight to the wall or to Unistrut, then hang the cover. At 33.9 lb empty plus conductors and devices, use anchors rated for masonry or hit blocking in a stud wall; drywall anchors alone won't hold it.

A screw cover box like the 241812 SC is the right pick where the box is a pull point or splice point you rarely open. The cover comes fully off for pulling wire, and the plated screws plus keyhole slots on the cover let you hang the cover on partially backed-out screws while you work, so you are not juggling it. If the box holds controls or terminal blocks someone opens weekly, a hinged door enclosure is the better choice, since removing and refitting screws every time gets old fast.

Painted carbon steel in ANSI 61 gray, which is the standard gray used across most industrial control and junction enclosures, so it will sit alongside existing B-Line and other ANSI 61 gear without looking out of place.

Yes, country of origin is the United States. That matters if you are buying for a government or federally funded job with domestic sourcing requirements on the submittal.

Yes for the typical indoor application. The 241812 SC uses 16 gauge carbon steel walls, which is the usual body thickness for a Type 1 screw cover box this size and keeps the 24 x 18 face from oil-canning when you pull conductors through it. The finished box weighs 33.9 lb, so two people make the install easier.
