Abstract
A larger active camming device including a plurality of opposed camming lobes, a cam head, a retraction system, and a connection system. The cam head includes a stem end and two parallel axles coupled to the stem end. The retraction system is a unique system comprised of a trigger, flexible trigger wires, control horns, and torsion springs. The control horns couple the trigger to the camming lobes and are configured to reduce buckling and allow greater camming range. The retraction system can also include a retraction locking mechanism. The locking mechanism is used to store the cam in a retracted and locked position until it is needed by the climber. When needed, the climber can easily unlock and extend the camming lobes with one hand.
