RockNRoller Multi-Cart is a U.S.-based maker of transformable utility carts widely used by touring musicians, DJs, AV crews, and stagehands. The company's signature product line — including models like the R2, R6, R8, R10, and R12 Multi-Cart — features a patented design that converts a single cart into eight different configurations (small dolly, large dolly, hand truck, platform cart, and various utility cart layouts) by adjusting a telescoping frame and removable end caps. The carts are designed around R-Trac no-flat wheels and offered with accessories such as R-Bags, equipment shelves, and decks for moving rack gear, mixers, speakers, and instrument cases.

The Multi-Cart became a fixture of the live-sound and music-production world after launching in the early 2000s, and the brand expanded into specialty configurations aimed at DJs, photographers, video production, and tradespeople. RockNRoller carts are stocked by music retailers including Sweetwater and American Musical Supply, and the company maintains a UK distribution arm in addition to its U.S. operation. Rather than building gear that makes sound, the brand occupies a load-in/load-out niche, focused on hauling other manufacturers' gear from van to stage in a single trip.
