Abstract
Abstract A refrigerator cabinet has each of the pair of front wheels or rollers supported on a front frame member at opposite ends thereof for vertical adjustment. Each of the wheels is rotatably supported in a housing having guide flanges on each side for cooperation with tracks which are formed between the front frame member and a track member to cause the housing to move only vertically when a screw is rotated. The screw is connected to the top of the housing for rotation relative thereto and threaded in a horizontal flange of the front frame member.
