  • Patent number: 4956897
    Abstract: A cam cleat includes at least two gripping members mounted in space apart relation. The gripping members provide a line gripping passage therebetween through which a line can extend. At least one of the gripping members includes a cam shaped gripping pawl mounted on a base member for pivotal movement relative to the upper gripping member. Movement of the gripping pawl toward the other gripping member closes the line gripping passage so that a line in the passage is gripped between the gripping members. Each gripping pawl has a pair of gripping surfaces arranged in symmetrical relation so that one of the pair of gripping surfaces engages the line during gripping. The surface allocated for gripping depends on the orientation of the gripping pawl relative to the other gripping member.
