Cut Sheet

The P5000 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 3 1/4" tall x 12 ga. thick, solid. Punched holes are also available for ease of installation. The advantage of a deeper, heavier gauge profile is to support heavier loads and mitigate deflection under load.

Our P5000 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).
