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 P3301 (back-to-back solid) channel is our 12 gauge channel that 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.


Features:

  • Product dimensions are 1 5/8" wide x 1 3/4" tall x 12 ga. thick, solid.
  • Punched holes are also available for ease of installation
  • This profile is used mainly for electrical applications because of its low profile and lower load carrying capacity
  • Often, a deeper profile overshoots the load capacity needs of the project.
  • Our P3301 is available in the following finishes: 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).
  • Made in the USA
