An exemplary bushing systemutilizes a bushing having a bottom plate having a plurality of holes from which filaments are drawn, and a plurality of support-receiving elements that are each configured to receive an elongated support. The support-receiving elements extend through the bushing generally along a longitudinal axis. A frame supports the bushing and includes a pair of horizontal rails upon which the supports rest. The horizontal rails comprise a treated surface that permits movement of the elongated supports relative to the frame in the longitudinal direction as the bushing expands and contracts due to thermal heating and cooling.
