Mounted on the side of a platform or scenery, this break actually lifts the scenery off its casters, preventing the wagon from shifting under active movements. A minimum of two brakes per unit are recommended. Heavy Duty Brakes hold an 800 lb. maximum load. 11" wide, 3" high. Regular duty brakes and optional extension spindle also available.
