Carton Flow racks feature internal rollers that move products in a single direction, similar to Drive-In Racks, and operate on a First-In First-Out (FIFO) basis for picking from the rear. Each section of the rack should store the same SKU. This system is ideal for items with a limited shelf life or those requiring regular turnover. The main advantages are the rapid movement of goods, reduced labor, and accurate and efficient inventory checks.
