Tylaska T40 Snap Shackles are designed for massive sailboats or for towing applications. With a breaking strength of 40,000 pounds, this shackle can handle sail loads on the largest of sailboats. A lanyard can be attached to a hole in the end of the trigger allowing for remote release; an ideal configuration for towing applications. The included locking pin provides extra security from accidental release. The T40 is intended for static load applications only and is NOT approved for lifting applications.
