Abstract
A cleat comprising a base plate and two dome-shaped high-friction surfaces, which secure a line or rope therebetween, the domes are connected to a ratchet which permits each dome to rotate in only one direction and the ratchets are arranged so that the domes rotate in opposing directions, drawing the line in and preventing the line from being withdrawn without manual release action. An adjustable tension head caps each dome and the domes float on low-friction washers, permitting limited and controlled line slippage whenever a pre-set line tension is exceeded. In another embodiment, eliptical collars and spring-loaded collar pieces surround the dome shafts to permit easy insertion of lines and provide an adjustment for different diameter lines.
