The Indicator Bin from Akro Mils (Akron, OH) is designed to help users manage inventory and avoid stock-outs. A simple, effective Kanban system, this consists of a single bin divided into primary and reserve stock. Once the primary stock is empty, the bin is turned around, revealing a bright indicator color, alerting users that the bin needs refilled soon.
A related product from Akro Mils allows users to attach Kanban Extended Label Holders to the front of storage bins. Users then slide out a bright orange Kanban flag to indicate when a bin needs refilled.
