The roll-around attachment will fit either of our 12 auto dolly. Once attached, you have unimpeded access to the wheel well areas (with the tires/wheels removed) and yet can still move your vehicle in any direction. A real boon to auto restoration projects, painting and body work. (now you don 't have to disturb your masked-off doors to move the vehicle!) also facilitates an orderly shop or garage and makes sweeping & cleaning so much easier too! The roll-around attachment is just one of the new accessories that make the auto dolly useful in so many ways in your shop or garage. Sold as a set of two, four needed per car.
