These end caps fit the "original" Yellow Jacket cable covers From Checkers Industrial. The yellow end caps contain five channels that allow running five separate cables, hoses, or pipes at a single time. Each channel can fit a cable or hose up to 1" in outside diameter while the center channel allows 3/8" more of cable space. The caps round off the ends of straight sections, intersections, and angled cable covers while still allowing the cords to run out through the end piece. Two separate pieces are complete with male and female "Dog-Bone" connectors that round off each end of covered cables. These products are proudly made in the USA.
