STEP 3

Assemble Bulkheads

The Universal TAU-II is comprised of multiple
bulkheads assembled to create a variety of
different system lengths and widths. Systems
are constructed with different bulkheads
depending on the size of the system that is
needed.

As illustrated in Figure 2, systems can be fully
parallel, fully tapered or a combination.

Every system requires a Front Support, a series
of Middle Bulkhead Assemblies and a Backstop
Assembly.
