Abstract: A cabinet for storing piano roll boxes comprises a five-sided housing with an open front. Arrays of horizontal support rods extend within the housing. The rods are arranged in pairs, with one rod of each pair being mounted near the housing open front and the second rod being mounted near the housing back wall. The first rod of each pair is higher than the second rod, so that the piano roll boxes tend to slide downwardly and contact the housing back wall. Two or more cabinets may be stacked on top of each other. Positive retaining means is included to hold stacked cabinets in alignment. The top cabinet may have the support rods of each pair in horizontal alignment for easy identification and removal of the piano roll boxes.
