The Rigging Rope Wrench takes Kevin Bingham's original Rope Wrench concept for adding friction midline -and turns it on its head! The Rigging Rope Wrench applies friction to a lowering line whilst anchored at the top of the tree. This means that not only is the device controllable from the ground, but the line can also be passed to the climber in the treetop, should they need to take control.
