ABSTRACT:
A D-shaped base fits tightly over a barrel to add ballast to the barrel. The base is perimeter weighted to increase resistance to tipping of the barrel. The interior circumference is designed to fit tightly on the barrel. The outer circumference includes a flat portion to resist rolling of the barrel if tipped over. As a result, if the barrel is tipped over, the base stays tightly fitted to the barrel, but if an automobile collides with the barrel, the base releases to reduce the possibility of damage to the automobile or barrel or base.
