P1000H3 - 1-5/8" x 1-5/8", 12 Gage; Round Holes on all three sides

P1000H3-No-Dimensions.png

Unistrut's P1000H3 has round holes on three sides of the channel, sized 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. This product also works well with our P9200 Telestrut for telescoping applications, such as solar racking, adjustable signage, and adjustable drop supports.

Product dimensions are 1 5/8" wide x 1 5/8" tall x 12 ga. thick; with round holes on three 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 of our Fittings can be attached through these holes, allowing attachment to all sides of the channel.

Our P1000HS is available in the following finishes: Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL) and Green (GR).
