For a safer and more reliable method of ensuring that the chains are tightly held down, you can use the Chain Ratchet Load Binder from B/A Products Co. This chain binder is designed to provide you with a method of securing the chains that does not put as much strain on the back and shoulder muscles as the lever chain binder sometimes does. It allows for slower, steadier tightening of the chains, allowing you to feel its strength right in the palms of your hands. There's less kinetic energy stored in the lever, lowering the risk of kickback during release. Simply hook the binder to the chains and start ratcheting to feel its strength.
