The underside has been re-sealed with some left over paint and the aluminum brackets for the electrical connections pointed out here with the blue arrows are done.
I finished a new set of legs for this module. This is a copy of the set I built for the first module last year and is covered in some detail in THIS POST.
These legs are adjustable to the 2 heights we set the layout up at. Both sets are shown here with each being at a different height.
