Stopper Set - No. 4-13

BLACK DIAMOND Stopper Set

Engineered for climbers who demand excellence, the BLACK DIAMOND Stopper Set is a time-tested passive protection essential for every trad rack. These stoppers are designed with a transverse taper, enabling versatile placements sideways in flares, constrictions, and shallow seams, making them invaluable for a variety of crack types and rock formations.

Each stopper features durable aluminum heads combined with galvanized steel cables, providing exceptional strength and reliability under load. The set is anodized by size for quick identification during climbs, and includes rounded edges that allow for easy removal and cleaning on the rock—smaller sizes have straight edges for improved surface contact.
