Abstract
A push-back rack with product support surfaces which are strung together and which move relative to the rack structure. In one embodiment, support surfaces include wheels or rollers, which roll on the rack frame. The support surfaces are connected together by flexible members. In another embodiment, the support surfaces are links of a chain and are connected together by pin and eye connections, and support rollers are provided on the rack rather than on the support surfaces.
