This EZ Claw Top Mount Kit is designed for use with 4-in-1 air and electric lines and is useful when mounting the tensioner to a toolbox style headache rack or other structure behind the truck cab where a mount that is parallel to the catwalk is required. Like all EZ Claw products, the brackets are laser-cut and CNC-bent for precise fit and installation. The combination of zinc-plating and a powder-coated finish resists rust and ensures longevity. Not recommended for roof or back of cab mounting. Rubber gasket included to reduce vibration and create a watertight seal. Hoses not included.
