Limits and Exclusions
There are no express warranties except as listed above. The warrantor shall not be liable for incidental or
consequential damages resulting from the use of this product, or arising out of any breach of this warranty.
All express warranties are limited to the warranty period set forth above. Some states do not allow the
exclusion or limitation on how long an implied warranty lasts, so the above limitations may not apply to
you.
This warranty gives you specific legal rights and you may also have other rights which vary from state to
state or country to country.

A. Foundation & Base Frame
1. Use pressure treated 2” x 4” (5cm x 10cm) to build a
foundation structure that has an outside dimension of
48” x 65” (1219.2mm x 1651mm).
3. Start with U-Channel bases (B3C) to insure a quick
and accurate layout.
Position all U channel bases on wood foundation. It
is critical that you allow 30 1/4” (767mm) between
front bases (B1C) and (B4D) 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.
