P3000SL - 1-5/8" x 1-3/8", 12 Gage; Long Slots

P3000SL-No-Dimensions.png

Unistrut's P3000SL has long slots on the back side for use with 3/8" threaded rod and fasteners. These slots can eliminate the need for field drilling and allow adjustability when installing. The slots are 3" long with 1" spacing.

This channel 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. 

Product dimensions are 1 5/8" wide x 1 3/8" tall x 12 ga. thick; with slots. The slots are 13/32" wide x 3" long, 4" on center and sized for use with 3/8" threaded rod or fasteners.

Our P3000SL is available in the following finishes:  Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD) and Stainless Steel (SS).
