Galvanised steel wiring trough 4×4×12

This Wiegmann RSCG040412NK wiring trough is a straight-section cable enclosure made from 16-gauge pre-galvanised steel with a galvanised finish and no paint. It carries a NEMA 3 rating and UL listing, and it has no knockouts so cables can enter at any point along the 12-inch length. The screw cover secures without a gasket.

Indoor and sheltered outdoor cable runs

It suits installers who need a simple, rigid raceway for power or control cables in dry or lightly damp locations where a gasketed seal is not required. Buyers who need a watertight or dust-tight enclosure rated NEMA 4, 4X or 12 should look at a different series.

Mounting pattern and usable depth

Verify that the 0.28-inch mounting holes on 28-inch centres match your support structure and that the 3.78-inch usable opening depth accommodates your cable fill and bend-radius requirements. The cover is held by screws, so allow access for a driver when planning the installation.
