For-Most's Double Alley System was the first to manufacture an alley system that provides two side-by-side adjustable alleys coming out of the tub. The reason this system works so well is that the cattle see a large 5' escape hole which they readily go through. Once inside the double alley, the cattle are then funneled into a single alley & then into the chute. This #1 Double Alley Bow is designed to begin that run by connecting the tub to the panels (either FM1004 6'3" or FM1016 8') that will be the first section of alley. Mounting pads on the alley bow provide for permanent installation to concrete. Please feel free to call our support staff for help in designing your optimal working facility.
