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

Please note: Black Diamond products can only be shipped to the U.S., Canada and Mexico.

Made in USA.

Comments about Black Diamond nForce Ascender:

Takes a little bit to learn the intricacies of these over the Petzl's, but they work very well.

At first, when I would pull the cam with my index finger (to lower the ascender on the rope) I would manage to open it completely, popping it off the rope! I've since trained myself to only grab the cam with the tip of my finger, staying away from the cam release trigger. It is nice to be able to open the cam completely with my index finger when I need to.

Also takes a little practice to keep it from "nose diving", where the cam will engage while sliding up the rope.

Otherwise, I'm sure I will enjoy these beauties for a long time.

Bottom Line Yes, I would recommend this to a friend

    Comments about Black Diamond nForce Ascender:

    Took a little bit to learn the different mechanics compared to similar ascenders such as Petzl, but after that, you realize the extra effort in the design is what sets these ascenders apart, and the best i've used.

    -The cams grabbed as advertised(I have yet to use these in wet and/or cold conditions), and released easily.
    -The teeth look like they would tear your rope up, yet were as smooth as any mechanical asenders i've used.
    -There was the frustrating "nose-diving", it was remedied by keeping nforce in a strict vertical position while moving upwards, no deviation.
    -I dropped one about 50 feet, on firm dirt, no problems. The extra moving parts cleaned out easily.
    -lightweight, extremely strong and stable for all the moving parts, etc, i couldn't be happier..
