Abstract: An improved container storing, shipping and handling rolling and shifting cargo is disclosed. Preferably, the container includes a base and a dome-like lid attachable to it. The base is formed with plural linear extending recesses having plural holes arranged in an array for receiving corresponding projections of plural chocks. Each chock has a chock base from which extend plural spaced projections for mating with the container's base. Each chock also includes a first working expanse extending upwardly at an oblique angle for restraining rolling cargo, a second working expanse extending vertically for restraining shifting cargo, and a third working expanse extending upwardly at an oblique angle different from that of the first working surface, the chock base and the working expanses forming a framing border structure defining the chock's open interior region.
