Abstract: A portable cleat of a generally two dimensional flat shape with a predetermined thickness having two arms (12) and (12A) projecting at opposite slight angles from a near central point. The arms form an ancient standard cleat shape for winding an elongated tension member (30) in multiple figure eights and finishing with an inverted loop to refrain from tying a knot. The main body (10) has a rear portion containing two apertures (18) and (20) of different sizes to adapt to various anchoring devices. The overall shape of the cleat considers the action-reaction law of physics and is specifically designed to enhance its use under kinetic tension forces. The main body also contains a plurality of holes (22) and (22A) allowing multiple cleats to be fastened together in modular fashion in order to multiply the overall strength yet maintain the designed functionality.
