P3001-No-Dimensions.png

Unistrut's P3001 (back-to-back solid) channel is our 12 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. For application examples, refer to our Application Showcase. 

Product dimensions are 1 5/8" wide x 2 3/4" tall x 12 ga. thick, solid. Punched holes are also available for ease of installation. This channel type provides a shorter alternative to its closest comparable, P1001.

Our P3001 is available in the following finishes:  Pre-Galvanized (PG), Unistrut Defender (DF), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD), Stainless Steel (SS or ST) and Aluminum (EA).
