Index

The Black Diamond Ascender Index is a very useful ascender for climbing with ropes. The Index will make it easy for you on the delicate or overhanging passages of your vertical climbs. The Index has a lock/unlock trigger for easy cam handling. With its ergonomic design, the dual-density handle offers a good grip. The lightweight body (200 g) of the Index helps to keep your harness, already full of material, from getting too heavy. The aggressive teeth of the Index bite well when the rope freezes.
