ABSTRACT:
This rope tightener is supported by or is engageable with a rope, line cord, or the like before it is manually tensioned and thereafter manipulated to draw the rope taut. The rope is stressed by threading the rope through a rectangular shaped loop in the device and then rotating the device in a plane parallel to the rope to twist the rope around a central body portion of the rectangular shaped loop in the device. After the first rotation of the device, the rope begins to wrap around itself. This lengthens the path of the rope and applies tension to the rope. The device is secured against reverse rotation by placing a reach of the rope under a reverse hook on the other end of the device. The device is a simple, one piece, rigid element, which is capable of giving a huge mechanical advantage in applying tension to a rope, line, cord or the like.
