US Patent 7036780 Rock-climbing machinery

A rock-climbing device that safely aids climbers during a climb is described. The rock-climbing device has two carabiners attached to a band which runs through a hollow tube. The climber is able to manually extend the tube over his or her head to an out of reach fixed anchor in the wall of the rock and safely attach the carabiner at the end of the device. This allows the climber to then attach the bottom carabiner of the rock-climbing device to his or her harness via a rope on the harness. The rock-climbing device allows the climber to safely and easily advance up the rock.
