Unistrut's P4004 (quadruple combination), often known as 16 gauge standard or deep back-to-back strut channel, is commonly used for electrical supports, mechanical supports, pipe, conduit, duct and cable tray supports, and other general framing.
This channel is ideal because it provides additional loading capacity and multiple connection points on a single plane versus a double or triple combination.
Product dimensions are 1 5/8" long x 3 1/4" wide x 16 ga. thick; quadruple combination.
Our P4004 is available in the following finishes: Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD) and Stainless Steel (SS).
