Unistrut P4001-20GR 1-5/8" x 1-5/8" x 20ft 16 Gauge Back-to-Back Solid Channel, Green E-Coat Finish

Unistrut P4000 is a 1-5/8in wide and 13/16in tall, 16 gauge steel channel. Often used for trapeze supports, seismic bracing, ceiling grids, pipe, conduit, duct, and cable tray supports, racks, and other general framings. This size and gauge of steel offer an advantage of a shallow, lighter profile to avoid over-engineering in a project that requires lighter loads.
