Black Diamond nForce Ascender

With a greater clamping force than conventional ascenders, the Black Diamond nForce ascender offers maximum grip on icy or muddy ropes. Anodized aluminum construction is lightweight, durable and corrosion resistant. Four-bar linkage drives body weight into the rope resulting in nearly a third greater clamping force than standard ascending devices. Flared rope slot fits a wide range of rope diameters, from 8-13mm; stainless-steel cam design can be installed and removed easily mid-rope. Spring-loaded stainless-steel cam opens wide for rope insertion; thumb-controlled lever offers one-thumb operation during ascension. Locking mechanism locks cam in either the open or closed position; engages and disengages with index finger via the cam trigger. Includes upper and lower carabiner clip-in points; thumb bump at top assists when descending short distances. Available in left- and right-handed versions, color-coded for easy recognition. Ergonomic polyethylene-coated grip provides a sure hold, even with heavy gloves; keeps hands from freezing and sticking in cold weather. Can also be used for self-belay or hauling gear.
