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

The P3300HS has round holes on the back side for use with 1/2" threaded rod and fasteners. These holes can eliminate the need for field drilling when installing a trapeze support, anchoring the channel to a surface, or for many other applications. This channel is commonly used for trapeze supports, seismic bracing, and anchoring to floors, ceilings and walls.


Features:

  • Product dimensions are 1 5/8" wide x 7/8" tall x 12 ga. thick; with round holes on one side.
  • The holes are 9/16" in diameter and 1 7/8" on center
  • The hole diameters and spacing match Unistrut’s general fittings so that nearly all our fittings can be attached through these holes
  • Our P3300HS is available in the following finishes: Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD), Stainless Steel (SS) and Aluminum (EA).
  • Made in the USA
