Patent number: 8544603Abstract: A fall restriction apparatus for climbers of wooden poles having a connecting component with at least a first bight portion adapted for connection to and retention within a center opening of a three slot-opening D-ring. The connecting component is sized so that when inserted within the central opening, it is restrained from rotating. The connecting component may have outwardly directed protrusions on at least its spine region. The affixed D-ring shape typically lies in a major plane orthogonal to a plane in which the remainder of the connecting component lies. Alternately, connecting component may be attached to other openings of the three-opening D-ring. The fall restriction apparatus also contains a buckle assembly which may have one or more cleats disposed on a rear surface to facilitate gripping a wooden pole.Type: GrantFiled: September 10, 2010Date of Patent: October 1, 2013Assignee: Buckingham Manufacturing Company, Inc.Inventors: James J.
