A large version of the Pageantry Innovations rolling racks, the AR-40 is built to accommodate deeper and larger selections of equipment and instruments. It is versatile and a handy tool to have around for any music program. It can haul gear from place to place, and it is sufficiently handsome and disappears under stage lighting well enough to be entirely appropriate to use as staging for percussion instruments or sound reinforcement equipment. Its flat-free wheels lock into place for security and stability.
