Abstract
The present invention relates to a dual stem active camming device including a plurality of compression springs independently coupled to a plurality of cam lobes. The compression springs are positioned between the trigger and the clip-in point of the cam to protect the springs from damage and allow the trigger to compress the springs upon retraction. A flexible stem tube is positioned over the portion of the dual stem between the trigger and the cable terminals. The flexible stem tube shields the trigger wires from debris and abrasion. A rigid yoke is also positioned over the dual stem between the stem tube and cable terminals. The rigid yoke prevents uneven lateral bending on the head of the camming device that may otherwise cause the device to pull out of a placement. The cable terminals are positioned between the outer cam lobes and on either side of the inner cam lobe.
