P4000HS - 1-5/8" x 13/16", 16 Gage, Round Holes

P4000HS-No-Dimensions.png

Unistrut's P4000HS has round holes on the back side for use with 1/2" threaded rod and fasteners (or smaller diameters with use of flat washers). 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 13/16" tall x 16 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 and easily adjusted.

Our P4000HS 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).
