LockJaw Synthetic Winch Lines are the most advanced winch lines available. Made from high strength synthetic fibers, LockJaw is stronger and vastly lighter than steel winch lines and shackles of the same size. THE PROBLEM: Metal winch lines are heavy, inflexible and inconvenient making them a safety hazard and taking up much needed time and effort to maintain. THE SOLUTION: LockJaw's patented design allows it to easily wrap around all kinds of anchor points. LockJaw Synthetic Winch Lines and Shackles are 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. USA.
