Stopper Set Pro #1-13

The original wired nut that helped launch the clean climbing revolution back during the 1970s on the floor of Yosemite Valley. Today, Black Diamond Stoppers are 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. The Stoppers are racked on a HotWire carabiner.
