An adapter for a recessed dispenser is disclosed. The adapter includes a frame configured to fit into a cavity of the dispenser. The adapter also includes a fastener for securing the frame to the dispenser. The frame includes two arms extending away from the cavity. The two arms are configured to removeably couple with a reduced-core diameter spindle. The spindle can expand/contract and is configured for use with a reduced-core roll of paper product. The adapter described herein allows for rolled product to be dispensed from an existing recessed dispenser where the rolls being dispensed have a larger outer diameter and a smaller inner core diameter than allowed by the original design of the recessed dispenser.
