Black Diamond Stopper Set #4-13

Time-tested stoppers with a transverse taper that allows you to place them securely in bottlenecks, flares, and shallow seams. The tapered shape extends versatility and adds multiple placement options. In addition, the classic shape (convex on one side, concave on the other) allows the unit to cam into position when loaded.
