B-Line Eaton series Type 3/3R junction boxes, 24" height, 6" length, 24" width, 3R, Screw cover, RTSC NK enclosure, Surface mounted, Medium single do

Yes. The 24246 RTSC NK carries a NEMA 3R rating and includes a rain hood, so it is built for outdoor wall mounting where falling rain, sleet and ice are the concern. It is not a washdown or hosedown enclosure, so keep it off applications that need 4 or 4X protection.

It measures 24 inches high, 24 inches wide and 6 inches deep, a medium single door style. The 6 inch depth is the number to check first if you are stacking terminal blocks or landing large conductors with bending room behind the cover.

No. The NK in 24246 RTSC NK means no knockouts, so the box ships blind and you punch conduit entries where your run dictates. Plan for a hole saw or knockout punch on the job, and on a 3R installation keep entries in the lower portion or use rain tight hubs so the rating holds.

Surface mount, using embossed thru holes in the back of the enclosure. The embossed holes hold the box body off the mounting surface so water can drain behind it rather than sitting against the wall. At 38.7 pounds empty, anchor into structure or blocking, not drywall alone.

A screw cover like the 24246 RTSC NK uses a flanged cover secured with plated screws. That suits pull boxes, splice points and terminations you open rarely, and it keeps the cover from being opened casually. If the box houses controls, breakers or anything you open routinely, a hinged door enclosure is the better call, because a screw cover means loose hardware in your hand every time you go in.

Carbon steel at 14 gauge, painted ANSI 61 grey. That is a heavy wall for an enclosure this size and gives you a rigid box that will not oil can when you punch it. Being painted steel rather than stainless, it belongs in ordinary outdoor and industrial locations, not in corrosive or coastal chemical exposure where stainless or a non metallic enclosure is the right spec.

It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. That matters on government, healthcare and education work where domestic origin is part of the purchasing spec.

It is finished in ANSI 61 grey, the standard grey used across most industrial control gear and switchboards, so a bank of these will read as one assembly alongside existing equipment. Useful if you are standardizing enclosures across a plant or campus.

The enclosure weighs 38.7 pounds empty. One person can manage it on a bench, but hanging a 24 by 24 box at height is a two person job once you factor the rain hood and getting fasteners started through the embossed thru holes.
