Abstract: A storage bag which is supported by and maintained upon a stackable storage rack is disclosed for handling, storing and moving items of irregular shape or configuration in a manufacturing, shipping, warehousing, or receiving facility. In the preferred embodiment of the present invention, the storage bag is hung on a device that is supported by the storage rack. This hanging device can be moved from storage rack to storage rack and can be loaded or unloaded from its top. The use of this hanging device permits the bag to be filled while in place in the storage rack and, therefore, easily moved with a forklift. In an alternative embodiment of the present invention, the storage bag is supported by the storage rack at its top and lower portions by strapping material to maintain shape and front retention devices to contain the contents.
