A conveyor belt support for a conveyor may comprise: a mandrel mountable to the far side of the conveyor and extending transversely toward the near side thereof; a member mountable to the mandrel from the near side of the conveyor that is slideable on and rotatable about the mandrel; and a roller supported by the member, wherein the roller is transverse to the conveyor belt when the member is mounted to the mandrel, wherein rotating the member in a first direction moves the roller to an operating position for supporting the conveyor belt and rotating the member in a second direction moves the roller to a position wherein the member and roller are removable from the support mandrel.
