REMOVING YOUR CAMBIUM SAVER

Tie a stopper know in climbing line and attach throw line to knot. Raise knot up and through large ring. Knot will then catch on small ring. Give a slight tug and friction safer will flip over limb. Now you can control descent with throw line. The use of throw line also insures your friction saver will not become stuck in tree.
