P3000 - 1-5/8" x 1-3/8", 12 Gage, Solid

P3000-No-Dimensions.png

This channel 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 1 3/8" 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, P1000.

Our P3000 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).
