Yes, within the limits of a NEMA 3R rating. The 10104 RTSCGV NK is a galvanized steel enclosure rated Type 3R, which covers outdoor use against falling rain, sleet and external ice formation. It also carries a rainhood over the cover. A 3R box is not rated for hosedown or windblown dust, so for washdown areas or dusty exteriors you want a 4 or 4X enclosure instead.

It measures 10 inches high, 10 inches wide and 4 inches deep, so it is a square enclosure with a 4 inch back box depth. That depth is the number to check against your conductor bend radius and any device or terminal blocks you plan to mount inside. Shipping weight is 6.4 lb.

No. The 10104 RTSCGV NK is the no-knockout version, so every conduit entry has to be field punched or drilled. Plan hole locations on the sides or bottom to keep water out of a 3R box, and use listed hub fittings or sealing washers at each penetration. If you want factory holes, order the knockout version of the RTSC series instead.

It is a surface mount enclosure with embossed thru holes formed into the back panel, so you bolt or lag it straight to the wall or to strut without drilling the box or breaking the 3R seal. The embossing keeps the fastener heads off the mounting surface and holds the box body away from the wall.

Screw cover. The cover lifts off entirely on plated screws rather than swinging on a hinge, which is the right choice for a pull or splice box you rarely open. If you need repeated access for troubleshooting, a hinged door enclosure is the easier box to live with.

The 10104 RTSCGV NK is listed to UL 50, the standard for enclosures for electrical equipment, and it is made in the US. That listing plus the Type 3R rating is what an inspector looks for on an outdoor pull or junction box. Field-punched entries still need listed fittings to keep the rating intact.

Order Eaton B-Line part number 10104 RTSCGV NK. The number reads out as the dimensions (10 high, 10 wide, 4 deep) followed by rain-tight screw cover, galvanized, no knockout. Swapping the NK suffix is what changes it to a knockout version, so keep NK on the order if you want a blank box.

It ships unfinished in grey galvanized steel, not painted. The zinc coating is the corrosion protection, so if you want a color match to other gear on the building you will be field painting it, and any field-cut conduit hole exposes bare steel that should be touched up.

The body is 16 gauge galvanized steel, which is the usual weight for a small single door outdoor enclosure of this size and stiff enough that a 10 x 10 x 4 box will not oilcan when you torque down the cover screws or hang it off strut.
