Abstract

A reusable shipping container adapted to resist damage to the feet of the container and to allow the fork straps to be replaced if the fork straps or the feet are damage. The container can also easily be adapted to accommodate the use of pallet jacks without reducing the capacity of the container or increasing the weight of the container. The container is also adapted to easily receive dunnage required to protect the material being shipped in the container.
