ABSTRACT:
Apparatus for use in climbing a tree, for example, in conjunction with a tree stand, comprises a metal strap having one end attached to one corner of a rectangular plate and the other end adjustably attachable to the diagonally opposite corner of the plate after encircling the strap around a tree. The plate has a lever extending across the other diagonal for twisting the plate so as to decrease the horizontal distance between the two strap attachments thereby tightening the strap around the tree and allowing a user to pull him or herself up on the lever. The apparatus is used by alternating upward stepwise movements thereof with upward stepwise movements of the tree stand, the user alternating his or her weight between the two items accordingly.
