Yes. The Eaton B-Line 12128 RTSCGV NK is a NEMA Type 3R enclosure, which covers outdoor use against rain, sleet and falling dirt. It has a rainhood over the cover to shed water, and the body is galvanized steel. It is not a watertight or washdown box, so keep it off surfaces subject to hose-directed water or submersion.

No. The 12128 RTSCGV NK is a no-knockout box, so every conduit entry has to be drilled or punched in the field. That is normal on a 3R enclosure, since you want entries placed where water will not track in. The body is 16 gauge galvanized steel, so a hole saw or a knockout punch set rated for sheet steel will handle it.

It measures 12 inches high, 12 inches wide and 8 inches deep, so plan on a 12 x 12 footprint on the wall with 8 inches of standout. At 11.5 lb empty, it is light enough for one person to hold while fastening.

It is a surface-mount box with embossed thru holes in the back pan, so it fastens flat to a wall or a strut rack with your own hardware. Embossed holes keep the fastener heads standing off the mounting surface, which helps keep the back of the box from trapping water. Mounting screws and anchors are not part of the box, so pick fasteners to suit the substrate.

Screw cover. The 12128 RTSCGV NK uses plated screws to hold the cover on rather than a hinge and latch. For a box you open often, a hinged-cover 3R enclosure is the easier choice; for a pull box or a splice point you rarely enter, the screw cover is fewer parts to fail outdoors.

Yes, 16 gauge galvanized steel is the usual body thickness for a 3R junction and pull box this size and holds its shape when you are pulling conductors through. For high-abuse areas such as loading docks or parking structures where a box takes impact, step up to a heavier gauge or a Type 4 enclosure.
