Bill, you don't have to use tandembox, do you? I would need to use the system with some solid stock drawers.

No. I think we used the 568 slides on a regular old 5/8" thick maple draw box. The only thing the servo drive does is add an electric arm that pushes the draw out of the cabinet. If I recall you have to push the draw in approx. 2 mm to activate it and then the electric arm pushes the draw the rest of the way out.
