Yale Cordage's Safari static line is a game changer for static rappelling construction. Unlike traditional parallel, bundled core constructions of nylon, the Kernmaster™ utilizes a unique 48-strand solution dyed polyester braided cover (mantle) and a braided nylon core that has been steam-stabilized. This design maximizes energy absorption, minimizes core fiber fatigue, enhances working flexibility, and eliminates in-field hardening. The result is a static line that delivers unparalleled performance and durability for all your rappelling needs.
