P1100HS - 1-5/8" x 1-5/8", 12 Gage, Round Holes
Unistrut's P1100HS 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. This is a great product for certain seismic bracing applications where slots are not allowed.
Product dimensions are 1 5/8" wide x 1 5/8" tall x 14 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 P1100HS 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).
