With the nForce Jumars by Black Diamond you get the best grip for jugging icy, muddy ropes (think Denali's West Buttress or some gnar-ed out fixed cord in the Fisher Towers), the nForce ascender generates more clamping force than conventional designs. The spacious grip accommodates gloves, and a 360-degree biner clip-in point allows full rotation of locking biners.

Climber's finger cuff

By Gabriel

Comments about Black Diamond nForce Ascender:

Great device, use it setting routes in the gym on over hangs and it works great! If you put your friends finger in the top and release the trigger the harder they pull, it pulls tight.


Great ascender

Comments about Black Diamond nForce Ascender:

Used these for over 80 aid pitches including twice up El Cap. I thought they were great. Smooth up, on, and off. Easy to trigger. I have tried a few other and these have been the best. Highly recommend.

Comments about Black Diamond nForce Ascender:

Bought this for canyoneering in southern Utah. Another piece of essential gear added to the quiver, hope I never have to use it.


best ascender

Comments about Black Diamond nForce Ascender:

I have a right-hand one. This works great on big rappels without a climb out. Also can be used in 3-1 haul system and self-rescue. Have used this on wet ropes in rain (but not ice or snow) still grabs! Easy on and off with one hand, also like how a push up the line takes teeth off automatically. Have not had a problem with it popping off, although I always have a biner through top hole. Best ascender in my opinion on market. Heavier than some but has huge hand area if you are using gloves. You can also operate trigger without sticking your finger through hole if using thicker gloves.


Great assender for price and conpany!
