Hobbyists and professionals who need to move their project cars around the shop can get some assistance with the Uni-Dolly from RD Enterprises. This tool is far more useful than individual dollies since the system’s two-inch-by-six-inch casters can be adjusted apart, from 30-60 inches. They’re also height adjustable, 14-21 inches. Uni-Dolly can be used regardless of whether your work-in-progress even has wheels, while supporting up to 9,600 pounds. Prices range from $440 to $990.
