CAUTION:
This is a two
person activity.
Module Rails are
unstable before
they are fully
secured to the
Support Angles.
Module Rails must
be held in place
by one person
while the second
person aligns and
secures them to
the Support
Angles. Failure to
do so could lead
to serious
personal injury.

Step 3: Attach the Module Rails to the Support Angles
Module Rails run in an E-W direction and are secured to the two Support Angles of
the Strongback (these are welded to the Strongback) using 3/8” x 1” bolts and
hardware. There are two Module Rails to install.
A. Align the Module Rail mounting holes with the holes of the Support Angle
and secure with 3/8” x 1” bolts and hardware. Finger-tighten for now. (See
Figure 3-1)
B. Continue in this manner and install the next Module Rail.
