B-Line Eaton series Type 3/3R junction boxes, 6" height, 4" length, 6" width, 3R, Screw cover, RTSCGV enclosure, Surface mounted, Small single door,

Yes. The 664 RTSCGV carries a NEMA 3R rating, which covers outdoor use against falling rain, sleet and external ice formation. It has a rainhood over the cover and galvanized steel construction to handle wet locations. A 3R box is not rated for washdown or dust-tight service, so if the location sees hose-directed water or heavy airborne dust you need a Type 4 or 12 enclosure instead.

It is a 6 inch height, 6 inch width and 4 inch depth galvanized steel box, so you need roughly a 6 by 6 footprint on the wall plus clearance for the rainhood above the cover. It weighs 3.1 lb, light enough for a single fastener pattern into block, stud or strut.

There are 3 knockouts, all on the bottom of the box. That is deliberate on a 3R enclosure: bottom entry keeps water from running down a conduit into the box. If your run comes in from the top or the back, you will have to punch your own opening and seal it, which compromises the 3R rating unless you use a listed rain-tight hub.

Surface mount, using embossed thru holes formed into the back of the box. The embossing stands the mounting holes off the back wall so the gasketing surface and interior stay sealed. Fasteners and anchors are not part of the box, so pick them for your substrate.

Screw cover, secured with plated screws. There is no hinge and no latch, so you need clearance and a screwdriver at the box to get in. For a location where an electrician opens the box regularly, a hinged-cover 3R enclosure is the easier choice; for a terminate-and-close junction point, the screw cover is fine and holds the seal evenly all the way around.

16 gauge galvanized steel, supplied unfinished in its natural grey galvanized state. No paint or powder coat, so if the spec calls for a finished color you will need to prep and coat it in the field. The galvanizing is what carries the corrosion protection outdoors.

It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. That plus the NEMA 3R rating is what an inspector looks for on an outdoor junction box.

The part number is 664 RTSCGV from Eaton's B-Line series. It ships as the box and its screw cover together, with the rainhood and the plated cover screws. No panel, terminal blocks, hubs or conduit fittings are included, so those get ordered separately for the job.
