The newly designed Black Diamond Index Ascender pushes the boundaries of performance with some truly revolutionary features. The ergonomically designed dual density grip surfaces on the cam and handle dramatically improve comfort while the new light weight frame makes it easy to push up all day on those long big wall ascents.

The unique trigger finger release action on the cam allows operation with your index finger, providing a more natural movement that is easier to use on an unweighted rope. You can still do it the old fashioned way as well – switch between thumb and finger and keep going for longer. The large clip holes provide compatibility with a wide variety of carabiners and the aggressive teeth are great for gripping icy ropes in colder weather.

Available in left and right handed models, the Black Diamond Index Ascender is the perfect choice for all rope sports that involve long ascents.


Design features:

  • Trigger finger release for easy operation.
  • Lightened frame so you can carry more on your rack.
  • Aggressive teeth to grip icy ropes.
  • Left and right handed models for versatility.


Ideal for:

  • Cold Weather
  • Climbing
  • Snow sports
  • Overseas adventure

  • Weight: 200g
  • Materials: Aluminium frame, stainless steel cam, rubber handle
  • Compatible rope size: 8mm – 13mm
