Time-tested passive pro, Stoppers are a direct link to the original chocks that started the clean climbing revolution. 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
Rounded edges for easy cleaning (smaller sizes are straight for better surface contact)
*Sizes 1 and 2 are for direct aid only
