The Kouba Alu is a set 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; moreover, 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.
Kouba is a Czech company that, thanks to its experience, specializes in climbing equipment, creating and assembling all products in the Czech Republic. It also boasts important collaborations with well-known companies such as Rock Empire and Omega Pacific, for which it manufactures components or entire products. Always attentive to the needs of climbers, it has a wide range of anchors available.
