Rugged ratcheting chain binder accommodates either Grade 70 transport chain or Grade 80 alloy chain tie downs, and is designed with features to make securing a load faster and safer than ever: Quick to install with three positions: ratchet extension, ratchet take-up, and a free spin setting for quick adjusting in either direction. Folding handle keeps the mechanism out of the way after the load is secure. Easy to store - simply place in the locked position and it's ready to hang. Tamper-resistant design; use a long shank padlock (not included) to lock to the tie down. Proof-tested and heat treated for durability; satisfies CVSA and DOT requirements. For use with either 3/8" or 1/2" chain.
