Black Diamond Pro Stopper Set #1-13

A complete passive protection nut set covering the full crack size range from thin finger placements to large hand slots, the Pro Stopper Set #1-13 from Black Diamond uses aluminum heads on stainless steel cables across all 13 sizes. The set runs from size #1 through #13 with individual stoppers weighted from 0.25oz (#1) to 2.5oz (#13) and a total rack weight of 1 lb for all 13 pieces. Strength ratings scale with size: sizes #1-2 rate at 2kN for micro placements where bomber strength is not achievable, #3 at 5kN, #4-5 at 6kN, and #6 through #13 at 10kN for the mid-to-large placements that form the working backbone of a trad rack.

Covering a placement range from approximately 4mm at #1 to 35mm at #13, the Pro Stopper Set #1-13 delivers a complete passive protection system from a single purchase — sized, weighted, and rated to handle everything from micro tips placements on granite faces to large constrictions in wide cracks where a cam would be the only alternative.
