A caster device includes a base attachable to a supported item, one or more rolling elements that interface with the base to facilitate rolling of the supported item along a support surface, and an external sleeve coupled to the base for adjustable vertical positioning of the external sleeve relative to the base. The external sleeve can be placed in a first vertical position relative to the base where the rolling element(s) do not contact the support surface, and in a second vertical position relative to the base where the rolling elements do contact the support surface. A rimguard may be rotatively coupled with the external sleeve so that as the external sleeve is rotated to the first vertical position, the bottom rim of the external sleeve rotates relative to a rimguard inner surface and a rimguard outer surface does not rotate relative to the support surface.
