Genuine replacement rope bridge for the TreeMOTION harness. If the green mantle on your TreeMOTION bridge is ruptured (by cutting, heat or abrasion) or the bridge rope diameter has changed in any way it should be replaced immediately with a genuine replacement bridge. A competent person should undertake the replacement process. The stopper knots must be able to stand a 2kN (200kg) force and the knot tail length should be 5-times the diameter of the rope bridge. Make sure the bridge stopper knot is properly set and dressed. Download the TreeMOTION flowchart below for more information.
