The Hammond C3R363612SC is a 36 x 36 x 12 in (914 mm x 914 mm x 305 mm) Type 3R junction box from the C3R SC Series, built from painted galvanized steel with a lift-off screw cover and easily removed knockouts on the bottom of the enclosure. It is designed for use as a wiring/junction box, for electrical contractors, facilities teams and panel builders who need a box that is protected against rain, sleet, snow and dripping water.

Construction is formed and spot welded 16 or 14 gauge galvanized steel, with a drip-shield top and seam-free sides, front and back. The slip-on cover lifts off once its plated steel screws are removed, and a padlocking hasp lets you lock it. The enclosure and cover carry an ANSI 61 gray powder coating over the galvanized steel. A grounding kit is provided; the design uses no gasket.

Hammond's drawing for the C3R363612SC shows an overall width of 36.55 in at the top, an overall depth of 12.32 in in side view and 12.98 in in bottom view, and embossed Ø0.28 in mounting holes on the back spaced 32.86 in x 20.00 in. The shipping weight is 130 lbs (58.97 kg). The bottom view shows knockout sizes of Ø0.88 in / Ø1.13 in (Detail Y) and Ø1.13 in / Ø1.38 in (Detail Z).
