First and second dollies are attached to opposite ends of a component such as an electrical box for a fab room. The assembly is moved on casters of the first and second dollies to an installation location. One side of the component is raised to allow the first dolly to be removed. As the one side is raised further, an arcuate frame member and an arcuate contacting surface of the second dolly provide a smoother transition to an upright position and prevent damage to the fab floor.
