Up to 0.4 in. (10 mm) of compression of the foam dividers is acceptable and may be
required in some instances

To accommodate a roof thickness greater than 5.5 in. (140 mm), order the optional
accessory kit. See “Tools and Materials” on page 4.
1. Using the tables, determine the number and
combination of foam dividers required based on the
roof thickness.

2. Place the ADB face down on a stable, protected, flat
surface.
3. Stack the foam dividers required and place them onto
the ADB.
4. Measure the full height, from the flat surface of the
ADB to the top of the foam dividers to confirm the
full height is equal to the previously determined roof
thickness.
5. Adjust the number of foam dividers to reach the
correct full height, as necessary.
