Engineered for hard-to-clean pitches, wild conditions and long days, the Index Ascender by BLACK DIAMOND is a robust workhorse for jugging in all weather.

Pushing the evolution of ascenders, the Index by BLACK DIAMOND allows trigger-finger access to help you manipulate the cam for easier operation low on a pitch or during hard- to-clean traverses. The dual-density grip and trigger of the Index by BLACK DIAMOND increase comfort for long days on the wall, and a large clip-in hole lets locking carabiners rotate 360 degrees for easy rigging.

With aggressive teeth, the Index Ascender by BLACK DIAMOND is primed for gripping icy ropes, and left- and right-handed versions add compatibility.
