Tracks are secured to the sides of a drawer and ride along sets of front and rear rollers at the front of a cabinet to guide the drawer for back and forth sliding in the cabinet. Downwardly inclined ramps are formed intermediate the ends of the tracks and act upon the rear rollers to cause the drawer to pivot about the front rollers to close the drawer automatically. Horizontally spaced tabs integrally formed with each of the tracks adjacent opposite ends thereof are spaced from the lower edge of the track different distances. On each side panel of the drawer, the tabs telescope into a kerf formed in the side panel to aid in supporting the drawer on the rollers and to assure proper location of the track on the side panel so that the ramps are positioned properly to obtain the desired self-closing action. |
