P3300T - 1-5/8" x 7/8", 12 Gage, Slotted
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).
