Time-tested passive pro for everything from granite walls to quartzite cragging—Stoppers are the descendants of the original chocks that started the clean climbing revolution.
Stoppers No. 5-11 racked on a Micron carabiner. Black Diamond Stoppers are an essential for every trad rack, designed with a transverse taper that permits sideways placements in flares and shallow seams. Anodized by size, they're quickly identifiable and rounded edges make for easy removal. Each Stopper is equipped with a durable, galvanized steel cable.
Durable aluminum heads and steel cables
Transverse taper is versatile in flares, constrictions and parallel cracks
