This Versa Mount Kit comes with an International Airfoil Adapter to make it easy to mount the system on International day cab semi tractors with cab-mounted airfoil using a C-channel profile. It is designed for use with 4-in-1 air and electric lines and is laser-cut and robotically-welded for long-lasting durability and strength. The zinc-plated and powder-coated finish resists rust and ensures longevity. The kit provides 11" of clearance off the back of the cab. This keeps air hoses and electrical cords from rubbing against the back of the cab and also keeps them adequately supported off the catwalk. Hoses not included.
