B-Line Eaton series Type 3/3R junction boxes, 8" height, 6" length, 6" width, 3R, Screw cover, RTSC enclosure, Surface mounted, Small single door, 3,

Yes, within the limits of a NEMA 3R rating. The 866 RTSC is rated Type 3R, so it handles falling rain, sleet and external ice formation on the enclosure, and it includes a rain hood over the cover joint. It is not a washdown or hosedown box, so do not use it where it will be sprayed directly or submerged, and do not count on it for dust-tight service. Body and cover are carbon steel, painted ANSI 61 grey.

Three knockouts are provided in the bottom of the box. Everything else is blank, so any top or side entry has to be field-punched. Bottom entry is what you want on a 3R box anyway, since penetrations on the top surface compromise the rain rating.

It is a screw cover, not hinged. The flanged cover lifts off completely once the plated screws are out, which is faster for initial wiring but means you are handling a loose cover every time you open it. If you need a door you can swing with a latch or padlock hasp for frequent access, choose a hinged-door enclosure instead of this screw-cover style.

It is 8 inches high, 6 inches wide and 6 inches deep, so you get a full 6 inch depth behind the cover for splices, terminal blocks or a small relay. Weight is 4.8 lb, light enough for one person to hold while setting the anchors.

It is a surface mount enclosure with embossed thru holes in the back, so the fasteners go through raised bosses rather than the flat back panel. That keeps the mounting screws off the sealing surface and preserves the rain rating. Anchors and screws are not supplied, so pick fasteners for your substrate (masonry, stud, or strut).

16 gauge carbon steel with a painted finish in ANSI 61 grey. That is the standard weight for a small exterior steel pull or junction box and it resists denting from ladders and carts. It is painted steel, not stainless, so in coastal or chemical environments expect to touch up any scratches or specify a stainless or non-metallic enclosure instead.

The 866 RTSC carries UL 50, the enclosure standard for electrical equipment, alongside its Type 3R construction. It is made in the US. That is the citation to hand an inspector for enclosure suitability; the wiring method and fittings inside still have to meet code on their own.

Order Eaton B-Line catalog number 866 RTSC. The number reads as the dimensions plus the series: 8 high, 6 wide, 6 deep, RTSC for the rain-tight screw cover enclosure. Useful if you are standardizing a site, since other sizes in the same family follow the same dimension-then-RTSC pattern.
