Load Binder is also known as chain binder, chain tensioners, normally used with grade 70 binder chains. Its main function is to tighten the steel chains around the loads. Load binders have 2 different styles: ratchet binder and lever binders.
With a ratchet chain binder, you can ratchet the binder to tighten things up and lock binders in place, while with a lever chain binder you can only tighten the chains with a fixed length, requiring additional steps to lock the lever binder.
