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
