I bought this unit to attach loads to my trailer in places where I don't have a trailer mounted ratchet or can't get a regular ratchet with a flat hook. . This gear can be mounted on a lap bar or even D-rings, making it much more versatile. Out of the box, these tail chain ratchet straps are heavy and strong. So far I'm really impressed with the quality. can receive 5 stars depending on how they perform in this area.
