The innovative Black Diamond nForce generates clamping power from both sides for more force than anything out there plus less wear on your rope giving you the best grip for jugging icy, muddy ropes. Dual side crimping design uses a four bar linkage that drives a climber's body weight into the rope. Fast cam manipulation by using thumb, trigger finger, or the edge of the frame. Grip accommodates gloves. 360 degree biner clip in point allows full rotation of locking biners. Left is BD orange color.
