This Synthetic Winch Line is the most advanced winch line available. Made from high strength synthetic fibers, LOCKJAW is stronger and vastly lighter than steel winch lines and shackles of the same size. Its flexible integrated shackle replaces both Bow and D-Shackles and maintains full strength while taking loads from many directions. LOCKJAW easily wraps around all kinds of anchor points. LOCKJAW is UV and abrasion resistant and will not rust. The exclusive lock securely holds the shackle closed when in use. Its lock is attached to the shackle preventing lost pins that are common with steel shackles. By design, the rope will only fall to the ground and not dangerously whip during failure. It also eliminates the chance of a metal hook launching as a projectile in the case of failure. Not rated for lifting. Patent Pending.
