Abstract
A cleat is formed by a base plate and two dome-shaped, high friction surfaces, which secure a line or rope therebetween. In one preferred embodiment spiralling grooves form the high friction surfaces with the grooves following symmetrical opposing spirals on the two surfaces to permit easy insertion while also providing strong gripping action even against tension in the line. In another embodiment three dome-shaped elements are secured to a base plate with alternating spiralled-groove patterns to provide a convenient two line cleat which is useful, for example, in securing both lines from a jib when sailing.
