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 Type A.
Available in Blue and Orange, in 35m and 45m lengths (1 eye splice), it's in stock at Gustharts as an authorised Cousin Trestec dealer, with free UK delivery on this order.
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 such as the ART SpiderJack and Petzl ZIGZAG, allowing the rope to feed smoothly through climbing devices while maintaining excellent durability.
Key Features & Benefits
- Professional arborist climbing rope designed for tree work
- CE EN 1891 Type A certified semi-static rope
- Durable double braid construction
- Made from 100% polyester for strength and stability
- No sheath slippage ("sock effect")
- Does not swell when exposed to water
- Patented splice for smooth feed through mechanical ascenders (SpiderJack, ZIGZAG)
- Flexible and easy handling during climbing operations
- Exceptional durability for professional arborist use
Technical Details
Designed for Professional Arborists
The ATRAX 11.6mm rope has been developed specifically for arborists who demand reliability and smooth performance from their climbing system. The stable polyester construction ensures consistent handling while resisting wear from friction devices, ascenders and regular tree work.
Why Choose the Cousin ATRAX?
Cousin Trestec is a French rope manufacturer with over 170 years of experience in rope and braid technology, and the ATRAX's patented splice was purpose-built for compatibility with modern mechanical ascenders like the SpiderJack 3 and ZIGZAG — a genuine advantage over general-purpose ropes that weren't specifically engineered for these devices.
Certified Protection Explained
EN 1891 Type A is the European standard for low-stretch kernmantle ropes used in rope access, work positioning and fall protection. Type A ropes are rated for direct access work — ascending, descending and positioning — making them more suitable than Type B ropes for professional rope access and arborist climbing.
Pairs Well With
Pair with a certified climbing harness and a mechanical Prusik or friction hitch device to complete your climbing system.
