Figure 3-1: Orientation of Module Rails to Stongback Mounting Tabs
CAUTION:
This is a two
person activity.
Module Rails are
unstable before
they are fully
secured to the
Strongback.
Module Rails must
be held in place
by one person
while the second
person aligns and
secures them to
the Strongback.
Failure to do so
could lead to
serious personal
injury.
