Another step forward in carabiner evolution, the Dyon uses a proprietary two-part gate to combine the benefits of smooth wire gate action with a keylocking closure. This unique combination gives it both high levels of performance and safety. The curved I-Beam construction on the spine keeps the weight to a minimum while providing a high level of rigidity and an incredible open gate strength of 11 kN. The patented SphereLock closure minimizes play between the gate and nose for enhanced safety and performance.
