The R12RT is the flagship of the RocknRoller® Multi-Cart® line, featuring rugged, foam-filled no-flat 10" rear wheels and 8" front casters that are designed to navigate just about any terrain, including gravel, grass, or other uneven surfaces with ease. The R-Trac® tires ride smoothly with excellent traction, similar to pneumatic tires, but without the hassle of upkeep or repair. The patented 8-in-1 cart can transform easily to adjust to various load sizes, allowing you to move large amounts of gear in no time at all. Extending from 34" to 52" in length, the R12RT has a weight capacity of 500lbs, but also folds small for storage or transport in a vehicle. The textured powder coated steel is durable and also reduces slippage during transport.
