A drum ring formed as a one-piece molded synthetic resin ring having an outer rim, an inner ledge radially inward therefrom and at least one appendage on the outer rim for placement of a mobility enhancer thereon. The ring can be installed on a typical material handling drum having a cylindrical side wall and bottom and top walls with an annular groove on the side wall adjacent each end wall. The ring is placed on the drum in such a way that the inner ledge of the ring fits inside an annular groove thereby securely attaching the ring to the drum.
