A. Foundation & Base Frame
1. Use pressure treated 2” x 4” (5x10cm) to build a foundation
stucture that has an outside dimension of 96” x 127”
(2438.4mm x 3225.8mm).
3. Start with U-Channel bases (B3LA) & (B3RA) to insure
a quick and accurate layout.
Position all U channel bases on wood foundation. It is
critical that you allow 61 1/4” (1556mm) between front
bases (B1LA) and (B1RA) for door placement. Measure
in all directions as shown in fig.1. Make sure the U-channel
assembly is a perfect square.
DuraMax must be installed on a level wooden platform
or a level concrete foundation.
The following are a list of lumber and sizes you will need.
2. Using exterior grade CDX 3/4” (19mm) plywood, cut
and fit together the sheets to form solid plywood floor as
shown. Foundation must be square and level.
