LockJaw® Synthetic Soft Shackles are a direct replacement to screw-pin shackles. Each shackle functions as a Bow, Anchor, and D-Ring shackle. LockJaw is impervious to rust and ice, making it the ideal choice for all weather conditions. The shackles are stronger than steel yet extremely light. If broken by overload, the shackle falls safely to the ground, minimizing the risk of potential injuries. All LockJaw shackles are made with a unique patented design and are proudly made in the USA. A Design Factor of 3:1 was used to determine the advertised Working Load Limit (WLL)
