ABSTRACT:
A circlet or lift ring is loosely affixed between the annular roll ridges of a conventional polyethylene drum to enable the drum to be secured to a conventional hand truck utilizing the standard hand truck hook. The circlet is formed with a diameter greater than the diameter of the drum, but smaller than the outer diameter of the roll ridges. The circlet is thus loosely, but securely affixed between the roll ridges with sufficient space between the circlet and the drum easily to be engaged by a standard hand truck hook to enable the drum to be handled easily on the truck.
