Kouba Stoppers Alu Nuts Anodized set climbing nuts colored from 1 to 9
Kouba Stoppers Alu Nuts Anodized set climbing nuts colored from 1 to 9 is made up of slightly curved nuts on one side, which can be positioned easily and quickly. This shape allows for better grip in the case of irregular cracks; furthermore, the curvature creates three contact points that make the nut more stable. Made of aluminum and secured to a steel wire, the set offers a wide range of sizes. The color allows you to quickly recognize the size.
