The 1486B72 is the longest 2.50 in x 2.50 in trough in the 1486 Series at 72.00 in (1829 mm). Like the rest of the series, it is designed to enclose and protect multiple wiring junctions from dirt, dust, oil and water, and its six-foot length reduces the number of joints needed on extended runs of small conductor bundles.

It is made from formed 14 gauge steel with smooth continuously welded seams. The butt hinged cover is secured with easily operated stainless steel screw clamps over permanently secured oil resistant gaskets, and 12 gauge external mounting feet are welded to the back. Trough and cover are finished in ANSI 61 gray powder coating.
