Description
The Notch Flow Adjustable Rope Wrench gives arborists greater control, smoother movement, and improved efficiency during SRS climbing. Designed in collaboration with Kevin Bingham and officially licensed from Singing Tree, the Flow builds on the proven ZK-1 concept with a fully adjustable friction system.
Its standout feature is the adjustable concave stainless steel bollard. Climbers can fine-tune friction settings to suit their rope, hitch, climbing style, and personal preference. This allows smoother descents, better hitch performance, and more efficient rope movement during ascent.
The Flow delivers ultra-low drag performance, helping reduce fatigue during long climbs. Many climbers choose it for smoother SRS movement and better rope management compared to traditional fixed rope wrench systems. Community feedback often highlights its easy adjustment and efficient climbing feel across different setups.
Built from hot forged T6 7075 aluminium, the Flow combines lightweight handling with excellent durability. Chamfered rope-friendly edges help reduce wear on climbing lines while maintaining smooth rope flow. The included stainless steel slic pin allows quick mid-line attachment for faster setup in the canopy.
The wrench works with ropes from 11mm to 13mm and integrates easily with the Notch Fusion Tether or other compatible tether systems. Multiple attachment points increase versatility for different SRS climbing configurations and auxiliary systems.
With a minimum breaking strength of 23kN and a compact 113g design, the Notch Flow Adjustable Rope Wrench offers professional climbers a lightweight and highly adjustable solution for modern single rope climbing systems. It delivers reliable performance, reduced drag, and customised friction control for efficient everyday climbing.
