Friction ring
The Friction Ring is a multi-purpose tool used in redirection or as a main anchor to reduce force on a friction system.
Description
The range of friction rings allows different techniques than those used with a rigging pulley. The small ring is mostly used for redirects, the large one mostly for the main anchor. The medium ring is adapted to both uses.
Friction is a major advantage, since it reduces the effort on the components of the rigging system that is used. It is easy to see in the use as main anchor. For the ground crew, slowing down loads is made simpler. Friction also gives the climber great comfort, since there is less strain on the upper anchor of the system. It is a valuable asset to improve comfort and thus safety.
