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. The rack pack includes 6 colors to coordinate with the most popular cam colors.
