We have given the "Vice Cleat" the nickname "Jaws". It is an emergency, temporary, mobile, jam cleat. A riding turn on a winch? A knot in a line under tension? In an emergency reach forward with these stainless steel locking pliers, with their large aluminium jaws and jam the rope behind a deck organiser or a pulley block. When they have locked the rope in place you can then release the tension on the rope behind them at the winch etc. and have time to sort the problem out. You may only need them rarely, but when you do, there is nothing else like them to do the job.
