A home appliance includes a rack that is mounted inside a cavity of the home appliance. The rack is mounted on rails that are located on opposite sidewalls of the home appliance cavity. The rack includes runners that are mounted on the rails. Each of the runners has a channel or aperture that receives one of the rails when the rack is mounted on the rails. One or more protrusions may be disposed on a surface of the channel or aperture of at least one of the runners. The one or more protrusions may be received in a channel formed on a surface of the corresponding rail. The protrusions may be rollers with vertical and/or horizontal axes of rotation.
