Arbpro Gemini Knee Ascender The Arbpro Gemini Knee Ascender is an innovative solution designed to improve efficiency and ease of movement during rope ascent. Developed for professional arborists, it replaces traditional bungee systems with a more controlled and responsive mechanism, helping streamline climbing performance. Spring Return System for Efficient Ascent Unlike conventional knee ascenders, the Gemini Knee features an integrated steel spring that automatically retracts and releases the cord. This design improves consistency and reduces effort during ascent, supporting a smoother climbing rhythm and increased efficiency. Secure Operation with Locking Mechanism The ascender is equipped with a locking lever that limits cam movement, helping reduce the risk of accidental rope release during use. This feature supports safer and more controlled operation when climbing. Flexible Compatibility with Footwear The Gemini Knee can be easily connected to a chest harness using the supplied snap. It also includes two interchangeable attachment options for the foot, allowing compatibility with Arbpro boots using the EZLoop system or standard climbing boots via an adjustable foot loop sling.
