Roller Bearing Stack racks feature the same inter-locking, stackable design as the standard Stack rack with the addition of a roller bearing tray that allows for effortless pull-out access and restocking of containers. The roller bearing feature creates drawer like operation of bins and boxes and has a "safety-stop" front retention lip to keep containers on the roller bearing tray. Same-size or different sized Stack racks and Roller Bearing Stack racks can be inter-stacked in a multitude of configurations. If you have a specific need and would like one of our experienced sales associates to help build the perfect storage solution.
