P1101 – 1-5/8″ x 3-1/4″, 14 Gage, Back-to-Back, Solid

Unistrut’s P1101 (back-to-back solid) channel is our 14 gauge channel that is commonly used for trapeze supports, seismic bracing, ceiling grids, pipe, conduit, duct and cable tray supports, racks, and other general framing.

A 14 gauge product is appealing to users who feel the 12 gauge alternatives provide an excess loading capacities than what is required from the design. It is also UL listed and CSA listed for use as a strut-type channel raceway.

Product dimensions are 1 5/8″ wide x 3 1/4″ tall x 14 ga. thick, solid. Punched holes are also available for ease of installation.
