Unistrut - 1-5⁄8” Framing System – Channel - P5500 T
12 Gauge Slotted Strut Channel P5500T (back-to-back slotted) has slots on the back side for use with 1/2" threaded rod and fasteners. The slots are an advantage during installation, eliminating the need for field drilling traditional slotted channel while retaining the adjustability of traditional slotted channel. This slotted option is popular because it’s adjustable and accommodates large diameter threaded rod yet has modest load capacity loss versus the solid version. It has 85% of the capacity of the solid version of the profile.
