Cantilever: As used in this disclosure, a cantilever is a beam or other structure that projects away from an object and is supported on only one end. A cantilever is further defined with a fixed end and a free end. The fixed end is the end of the cantilever that is attached to the object. The free end is the end of the cantilever that is distal from the fixed end.

Carabiner: As used in this disclosure, a carabiner is coupling link that is usually formed as an oblong metal ring with one spring hinged side that is used to open and close the ring.

Center: As used in this disclosure, a center is a point that is: 1) the point within a circle that is equidistant from all the points of the circumference; 2) the point within a regular polygon that is equidistant from all the vertices of the regular polygon; 3) the point on a line that is equidistant from the ends of the line; 4) the point, pivot, or axis around which something revolves; or, 5) the centroid or first moment of an area or structure. In cases where the appropriate definition or definitions are not obvious, the fifth option should be used in interpreting the specification.

Center Axis: As used in this disclosure, the center axis is the axis of a cylinder or a prism.
