The Work Winch is the most universal and easiest to use tie-down system ever made. Work Winches "plug in" to any I.T.S. series rack in 2 to 3 minutes. They are constructed of aluminum alloy and stainless steel with a PVC bearing. It is the only rust free tie-down system made and has a nearly unlimited lifespan. This is not a bolted-on aftermarket accessory, but an integral part of a System One I.T.S. series ladder rack. Everything you need is always right there - even the handle. Just lift the pawl and pull out as much strap as you need. Place the strap around the load and hook it to an anchor hole or crossmember. Take up the slack with the hand-wheel and tighten firmly using the handle. The handle can be kept permanently on the shaft or it can be left in a toolbox and used only when needed. When hanging it allows the shaft to rotate freely within it; when pushed forward, it will engage and operate the winch.
