Cut Sheet

Unistrut's P3001WT (back-to-back slotted) has slots on the back side for use with 5/8" threaded rod and fasteners. The wider slots are an advantage during installation, eliminating the need for field drilling traditional slotted channel while retaining the adjustability of traditional slotted channel.

This channel is commonly used for trapeze supports, anchoring to concrete, ceiling grids, pipe, conduit, duct and cable tray supports, racks, and other general framing. For application examples, refer to our Application Showcase. It has 85% of the capacity of the solid version of the profile.

Product dimensions are 1 5/8" wide x 2 3/4" tall x 12 ga. thick; back-to-back with slots. The slots are 2" wide x 11/16" long, 3" on center and sized for use with 5/8" threaded rod or fasteners.

Our P3001WT is available in the following finishes:  Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD) and Stainless Steel (SS).
