Abstract
Abstract Cabinet drawers are supported by a pair of runners each received within side grooves on the drawer. A first limit stop on the runners cooperates with a mating limit stop adjacent the rear end of the drawer to prevent the drawer from inadvertently being pulled completely out. A third limit stop is provided on the runners for cooperating with the second limit stop when sufficient upward force is applied to the drawers to cause the first limit stop to fail to contact, or to skip past, the second limit stop.
