ABSTRACT:
A drawer rail assembly having a roller mounting and retainer member that connects with a snap fit to the intermediate rail, specifically into a window opening in the intermediate rail, to mount and retain a roller between the upper and lower rails. The retainer has an axle extending from the body thereof, through the roller hub, has slots to receive shoulder flange portions of the intermediate rail cross member, and has hooks to engage one of the offset flanges of the intermediate rail. The interconnection of the slots and shoulder flanges and of the hooks and flange attach the retainer to the rail to support and stabilize the roller. The retainer also covers the roller to shield it, while simultaneously supporting and stabilizing it.
