The new Rope Wrench with Squirrel Tether is manufactured from aluminium, which ensures that twist and flex in the Rope Wrench system, is minimal. This means that the Rope Wrench remains in the optimal low friction position during ascent, (allowing the climber to achieve maximum climb efficiency), and ensures that the Wrench engages efficiently, as required during lateral movements and descent.
It works by using leverage to force the rope into an S shape and providing friction for a controlled descent. When engaged, the Rope Wrench acts much like a conventional descent device such as a Figure eight.
When not engaged, the Rope Wrench provides no interference with ascending the rope. This allows the climber to work an entire tree using Single Rope Technique.
