Hammond C3RWT1224G 12x12x24 In Type 3R Galvanized Wiring Trough

This short, deep 12 x 12 in trough packs a large cross-section into a two-foot length for compact outdoor junction points. The C3RWT1224G is a 12 x 12 x 24 in Type 3R wiring trough in unpainted galvanized steel, designed to protect multiple wiring junctions in outdoor environments against the ingress of rain, sleet, snow and the external formation of ice. It suits electricians, electrical contractors and facilities teams who need to protect multiple wiring junctions in one enclosure in outdoor installations.

The trough is formed and spot welded from 14 or 16 gauge galvanized steel and left unpainted. A drip shield top design helps shed rain, snow and sleet away from the enclosure, and a slip-on removable front cover is secured with screws, so the wiring can be reached by removing the cover screws.

Nominal size is 12 in x 12 in x 24 in (305 mm x 305 mm x 610 mm). The manufacturer drawing shows an overall length of 24.88 in, an overall cross-section dimension of 12.44 in, a front opening of 22.75 in x 10.42 in and an inside dimension of 11.86 in. At 24 in long, its back carries 4 mounting holes of Ø0.30 in, spaced 20.00 in apart horizontally and 9.00 in vertically. Shipping weight is 35 lbs (15.88 kg), packed in a box.

The trough is listed to UL870 Type 3R and CSA Type 3R, complies with NEMA Type 3R and IEC 60529 IP24, and is covered under UL File E186830 and CSA certificate LL21312. It is also marked REACH and RoHS compliant. Note that effective August 17, 2026 the grounding strap and padlocking hasp that were previously included are no longer provided with each trough, so plan for those separately if your installation calls for them.
