Abstract
The present invention may be used for climbing over a fence or a vertical barrier. A body may have a plurality of steps attached orthogonal to the body. The body may have a width and length to fit between two vertical bar fence elements and to position the steps generally perpendicular to a plane of a fence. A top hook may be attached to a top end of the body. A horizontal bar may be attached at a bottom end of the body generally orthogonal to the steps. A rotatable member may be rotatably attached to the body and may be spaced apart from the body by a pedestal.
