Propusher

ProPusher is a spring-loaded shelf pusher system for standard flat retail shelving. A paddle behind each row pushes product forward as items sell, so the front edge stays faced without anyone pulling stock forward by hand.
It suits boxed goods, pouches and small packaged items, the packaging that slumps, leans and falls back on a normal shelf. For bottles and cans in a cooler, a gravity-fed system is usually the better fit. See cooler racks for that side.
