Patent attributes
A roller assembly includes a roller body having a rounded outer surface, an end opening, and an internal cavity extending inwardly along an axial direction from the end opening and configured to receive a weight assembly including one or more weights, a weight holder received within the cavity and configured for holding the weight assembly within the cavity, and a retaining structure engaged with the roller body to retain the weight holder and the weight assembly within the cavity. The weight holder includes first and second engaging members to engage first and second ends of the weight assembly that are spaced in the axial direction, to limit movement of the weight assembly along the axial direction. At least one of the first and second engaging members is positionable in different axial positions relative to the other, such that the engaging members can accommodate changes in size of the weight assembly.
