Akro-Mils announces the expansion of its line of two-tone indicator bins, a single-bin Kanban system that helps control inventory. A new black/red color combination joins the original blue/orange bin colors. With this addition, there are now four sizes and two color combinations available. The bins simplify visual recognition when supplies must be replenished, and allow users to stock, pick, and flip contents. Users stock the bin using the divider to designate volume for the inventory reserve; pick from the large stock area of the bin until reaching the divider; flip the bin to the reserve side to show inventory levels are low; and replenish the bin. The bins are available in 12-inch and 18-inch depths for use on standard wire shelving, steel shelving, and pick-rack systems.
