An improved refrigerator door is provided with a metal outer panel and upper and lower plastic end caps installed on top and bottom edges of the door. The caps include grooves to receive flanges on the edges of the panel, thereby mounting the caps to the panel. The caps include plugs for receipt in a vertical channel in the panel. A bushing is snap fit into the upper cap without the use of hardware fasteners. Electric wires and a water line extend downwardly through the bushing to an ice and water dispenser in the door.
