Black Diamond nForce ascender

Giving you the best grip for jugging icy, muddy ropes, the nForce ascender generates more clamping force than conventional designs.

trigger finger or the edge of the frame.

Four-bar linkage.
Trigger-finger cam.
Full-sized molded hand-grip accomodates gloves.
Large carabiner clip-in hole.
2 colors for easy recognition of right and left versions.
