A system for abating noise associated with the use of weight stack plates comprising a stack of plates for a weight lifting machine, each plate having a central vertical hole therethrough and supplemental guide holds therethrough and a horizontal hole from one edge to the center vertical hole perpendicular to the central vertical hole elastomeric material operatively associated with at least the upper and lower surfaces of the plates of the stack to abate noise normally associated with the movement of the plates; and a pin positioned vertically through the center holes of the plates of the stack, the pin being formed of a plurality of axially aligned segments coupleable one to another, along a common axis with spacers associated with each segment corresponding to the thickness of the elastomeric material between adjacent plates, the pin being formed to have a horizontal hole in each segment aligned with the horizontal holes of the plates.
