Black Diamond NForce Ascender Right

Giving you the best grip for jugging icy, muddy ropes, the nForce ascender generates more clamping force than conventional designs. It uses a four-bar linkage that drives your body weight into the rope and fast cam manipulation is achieved by using the thumb, trigger finger or the edge of the frame. The grip accomodates gloves, and a 360-degree biner clip-in point allows full rotation of locking biners.
