CUT TO A CUSTOM LENGTH? MAY SAVE ON SHIPPING
HOW WOULD YOU LIKE IT CUT?
Some cutting jobs allow us to use ground shipping rather than LTL, yielding significant freight savings. A customer service associate will contact you to confirm the cut list and shipping and freight costs prior to finalizing your order. eg - 4 cuts per stick x 5ft per section
12 Gauge Welded Strut Channel with Slots P3301T (back-to-back slotted) has slots between the two profiles on the welded side. 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.
Features:
- Product dimensions are 1 5/8" wide x 1 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 P3301T is available in the following finishes: Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD) and Stainless Steel (SS).
- Made in the USA
