    Abstract: An improved mandrel construction for paint rollers characterized by the provision of a laterally movable inboard mandrel and a fixed outboard mandrel with the outboard mandrel having generally yieldable fingers normally engaging the interior of a replacement roller cover telescoped thereover. Mating locking surfaces are provided on the inboard and outboard mandrels so that when the two are brought together by relative axial movement and the locking surfaces thereof interengage, the fingers on the outboard mandrel are contracted to permit the roller cover to relatively freely fall therefrom.
