ABSTRACT:
A top weight adapted for vertical adjustment when disposed at the top of a weight stack in a suspended weight exercise machine having guide rods on which the weight stack slides, and a central pick-up rod which engages the weight stack for suspension thereof. The top weight includes a plurality of cavities open at the bottom to permit installation of insert weight plates therein. A slot opening extending through the entire width of the top weight permits vertical adjustment of the central pick-up rod when the top weight is mounted thereto along a vertical direction. This vertical adjustment accommodates manufacturing tolerances in the weight stack which would otherwise prevent a selector pin from interconnecting the weight stack to the central pick-up rod.
