This innovative idea from Kevin Bingham takes the Rope Wrench one step further. A Rope Logic FIX tether connects the Rope Wrench to a DMM Pinto Rig pulley. This rigging system allows a groundsperson to handle more weight without the use of a traditional friction brake. Available with the Rope Wrench as well. #50083 The FIX Tether is made from 8mm Bee Line and a special composite material that makes it incredibly stiff for ideal performance. Extreme caution should be taken in determining appropriate load size. The Rigging Wrench only provides a single level of non-variable friction or braking force.
