As the name implies, our special adjustable lever style chain binder is designed with a built-in adjustment feature for a safe, quick and easy solution to attain proper tension for cargo with a working load limit of 5400 lb/2450 kg that has been tied down with 5/16 in to 3/8 in sized chains. Simply rotate the adjustable end and extend or retract it to achieve the length you want. No more bouncing back and forth from one link to another trying to find a secure fit. The Adjustable lever style chain binder also comes equipped with a lock pin, making it one of the safest binders in the cargo control industry. The formed steel handle offers optimal strength and leverage so you can securely tighten down or easily release your load with a firm push. We recommend never using a cheater bar or other handle extenders to tension the load as this could potentially cause serious or fatal injuries and/or cargo damage. The 3/8 in clevis grab hooks have been engineered to provide you with the high-quality durability you need to secure your cargo. These hooks are simple, reliable and have been coated in a zinc plated finish to protect them against corrosion.
