ABSTRACT:
A sliding panel includes a frame having top, bottom and side members. Expanders rotatably supporting rollers are partially disposed within the top and bottom members and are displaceable against spring tension inwardly and outwardly of said members. Clips are provided for retaining the expanders partially disposed within the top and bottom members and for limiting the outward displacement of the expanders. The arrangement described provides self-leveling of the rollers along the entire width of the panel.
