Hammond C3RWT1224 12x12x24 Inch Type 3R Galvanized Wiring Trough

The C3RWT1224 is a 12 x 12 in, 24 in long Type 3R wiring trough, the largest cross-section in the C3RWT series in its shortest length. It is intended for outdoor wiring junctions with a high conductor fill in a compact two-foot run.

Like every trough in the C3RWT series, it is formed and spot welded from galvanized steel (the series is made in 14 or 16 gauge), and both the enclosure and cover are finished in ANSI 61 gray powder coating, which is why the part is listed as Galv/Gray. A drip shield top design protects the enclosure against rain, snow or sleet, and the slip on front cover removes for access and is secured with screws.

The nominal size is 12 in x 12 in x 24 in (305 mm x 305 mm x 610 mm), with a shipping weight of 33 lbs (14.97 kg). The part drawing shows an overall length of 24.88 in and a 12.44 x 12.44 in overall section including the drip shield, a front opening of 22.75 x 10.42 in, and inside dimensions of 11.86 x 11.86 in. Mounting is through 4 embossed holes of 0.30 in diameter on the back of the enclosure, spaced 20.00 in lengthwise and 9.00 in vertically.

The C3RWT1224 is listed under UL870 Type 3R (UL File # E186830) and CSA Type 3R (CSA Cert. # LL21312), and complies with NEMA Type 3R and IEC 60529, IP24. To meet UL870 - 2008 requirements the series specification sheet shows a bonding stud on the cover and a ground stud in the enclosure. The part is RoHS and REACH compliant. Note that effective August 17, 2026 the grounding strap and padlocking hasp previously included with each trough are no longer provided.
