Abstract: A rope tie-down clamp apparatus is provided for quickly and easily tightening and securing a rope between two points. The rope is formed with a loop at one end, and the end of the rope is secured to the housing of the clamping apparatus. A passage is provided through the housing for the length of rope, and the clamping cam is mounted for movement in the housing from a first position engaging the rope in the passageway to a second position out of engagement with the rope. The clamping cam may be manually moved out of engagement with the rope to facilitate adjustment of the rope length and the loop formed by the rope and the housing of the clamping apparatus.
