$

P4000 – 1-5/8″ x 13/16″, 16 Gage, Solid

This channel is commonly used for trapeze supports, seismic bracing, ceiling grids, pipe, conduit, duct and cable tray supports, racks, and other general framing.

Product dimensions are 1 5/8″ wide x 13/16″ tall x 16 ga. thick, solid. Punched holes are also available for ease of installation. The advantage of a shallow, lighter gauge profile is to avoid over-engineering in a project that requires supporting lighter loads.

Our P4000 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) and Aluminum (EA).
