ABSTRACT:
A climbing and support apparatus and method to facilitate performance of maintenance activity in a tree by an arborist. Briefly, the apparatus includes dual annular rings having dimensions in accordance with a predetermined geometric relationship disposed at proximal and distal ends of a nonuniformly compliant element, typically manufactured of high strength webbing. Serial passage of a rope with a modified portion through the rings and about a desired support location in accordance with a predetermined sequence permits ground level installation of the apparatus in a remote location in the tree. The apparatus is configured to prevent abrasion damage to both the tree and climbing rope and may be safely and reliably retrieved from ground level upon completion of desired maintenance activity in the tree.
