Start by installing the inboard sections of Module Rail first and work outward.
A. Referring to Figure 4-1 for orientation of the inboard Module Rails, position
the first section of Module Rail (with its angle cut end positioned north) at the
northern most position on the Cross-Bars. Align the Module Rail mounting
holes with the holes of the Cross-Bar mounting tabs and secure with 3/8” x 1”
bolts and hardware. Finger-tighten for now. (See also Figure 4-2)
B. Install the next Module Rail creating a butt joint with the previously
installed Module Rail.
C. Position Module Rail with its angle cut end positioned south and its square
cut end butting up to the end of the previously installed Module Rail. Secure
with 3/8” x 1” bolts and hardware. Finger-tighten for now.
