The LEWISbins 4 Inch Tall Plastic Shelf Bins are engineered to fit shelving of 12", 18", and 24" depths, optimizing storage efficiency. They feature a raised hopper front that enables up to 35% more material storage than comparable bins, enhancing both picking and inventory control. Each bin includes a full-length divider that locks securely into place, creating a secondary storage compartment. Additionally, the rolled rim design and molded-in rib structure enhance the bin's integrity, reduce damage risk, and prevent vacuum lock when bins are nested. These features make the LEWISbins an ideal choice for maintaining an organized and efficient workspace.
