It allows the immediate release of the rope by a short upward and backward pull.Nylon cleats offer very good value for money, for both production builder and sailor alike.

Aluminium cleats are highly successful in providing a complete answer to rope burn. They are unaffected by the heat generated by a rope surging back through a cleat as well as being suitable for sub-zero temperatures. Uses #6 fasteners.
