LOCKJAW™ Self-Adjusting Locking Pliers provide the versatility of standard locking pliers. However, that’s where the comparison ends. Traditional locking pliers require two hands to adjust the jaw opening for each task; LockJaw’s patented locking mechanism allows the jaws to automatically adjust to any size object for simple one-handed operation. Whether grabbing something thick or something thin, LockJaw™ Self-Adjusting Locking Pliers make jobs faster and easier.
