Unistrut's P3300T 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 7/8" tall x 12 ga. thick. Slots are sized for a 1/2" threaded rod or fastener. This slotted option is popular because it's adjustable, yet has modest load capacity loss versus the solid version. It has 85% of the capacity of the solid version of the profile. Our P3300T is available in 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).
