using the 3/8” hardware supplied. Set the Stack up in the bed and loosely

floor rail away. Refer to Figure 4.
8. Measure from the 18” Extension Pipe slip joint to the Extension Pipe.
Mark and cut the shorter side of the 20” Elbow to the required length so
that it lines up with the Extension Pipe. Cut the Extension Pipe in a place
where the Flex Pipe can be placed between the Extension Pipe and the
20” Elbow. It may be necessary to cut the 20” Elbow again as well as the
Flex Pipe to ensure proper fit. Refer to Figure 5.

the Flex Pipe to both the 20” Elbow and the Extension Pipe. Be sure to
slide the required Clamps over the 20” Elbow and Flex Pipe before
