Opposed cantilevered adapters are provided for supporting a roll of material. The adapters have a roll bearing surface, a projection surface with a first end and a second end such that the first end is coterminous and substantially perpendicular to the roll bearing surface at each point along an interface formed therebetween, and an actuating surface angularly coterminous with the second end of the projection surface. |
