Abstract
Abstract An improved dolly is provided for supporting, for example, a stack of receptacles, and which is constructed in an improved manner to incorporate a pair of side strips, each formed into a channel, so as to permit the dolly to be stacked easily on top of a similar dolly for shipping convenience, and to incorporate a pair of upstanding, transverse end strips, which serve to prevent the receptacles and the stacked dollies from sliding or rolling off the dolly.
