Schaefer has combined the traditional incline shelf and roller live storage principles in the KDR Gravity Flow Rack Shelving, creating a non-powered storage and retrieval system. Gravity flow rack reduces travel time and increases order fulfillment speed, while providing an organized, high-density storage system. Designed for fast-moving small to medium-sized parts with high volume, it offers a perfect blend of heavy-duty ruggedness and ergonomics, making it ideal for assembly line-side operations, and traditional first-in/first-out applications. KDR levels are fully adjustable in 0.25" high or 1" angle increments. Width between the roller tracks is also adjustable in 0.1875" increments, enabling the use of virtually any container. KDR Systems are fully compatible with Schaefer Bins & Containers.
