Product information & specifications
Cousin ATRAX 11.6mm Climbing Rope
The Cousin ATRAX 11.6mm Climbing Rope is a high-performance arborist rope engineered for tree work, climbing and professional forestry applications. Built using a durable 100% polyester double braid construction, this semi-static rope offers excellent dimensional stability, smooth handling and long-term durability for demanding arboricultural environments.
Certified to CE EN 1891, the ATRAX rope is designed for reliability when used with modern climbing systems and mechanical ascenders. Its carefully engineered construction prevents sheath slippage – often referred to as the “sock effect” – ensuring consistent performance and safe rope handling throughout its working life.
The rope remains flexible and smooth even after prolonged use, while the polyester fibres resist water absorption and swelling. This ensures the rope maintains predictable handling characteristics in wet conditions, making it well suited for year-round tree work.
A new patented splice has also been specifically developed to work efficiently with mechanical ascenders, allowing the rope to feed smoothly through climbing devices while maintaining excellent durability.
