This Hinged Flange Mount Bracket Kit is designed for use with 4-in-1 air and electric lines. It is laser-cut and robotically bent for long-lasting durability and strength. The zinc-plated and powder-coated finish resists rust and ensures longevity. Keeps hoses from rubbing on the back of the cab and catwalk. The brackets' ability to hinge allows the stainless steel line from the Line Saver to travel centered in the roller guide on tractors with a shorter wheel base. Hoses not included.
