The critically acclaimed Rock 'N Rollers reduce time and effort moving equipment by over 50%. The patented design instantly transforms into any of 8 configurations to fit any equipment size or shape replacing the need for 8 different carts. Multi-Carts quickly and ergonomically move huge amounts of gear yet fold small for storage. All models are now equipped with new patent-pending G-Force wheels and casters which are strong and light with a super quiet ride. New textured finish resists equipment slippage better than smooth finishes.
