A ring is mounted, in horizontally surrounding relation, on a plastic drum adjacent but short of the upper end thereof; the ring being fixed on the drum, and structurally designed to provide an annular lip extending coaxially about the drum in radially outwardly spaced relation to the drum sidewall whereby the lip is exposed for engagement by the gripping device of a lift-type industrial truck employed to lift and transport such plastic drum.
