4. Each loosely suspended rack arm/drive pipe assembly will have the rounded ends of the 112582 couplers open
at the rack arm end. With assistance, or a lift machine, guide the
plain
end of another 105S156 drive pipe through
the drive roller of the next rafter, and splice onto the coupler using 1/4"x1-1/2" bolts (FAG106B) and 1/4" lock nuts
(FALF15B). See diagram below.
5. Based on drive pipe layouts on the following page, continue adding 105S156 drive pipe until the bay where the

the plain ends and be spliced with FA4470B Tek screws.
Tek screws MUST be installed on the TOP side of the
drive pipes to avoid interference with the drive rollers during operation.

Remember that each end of the drive pipe assembly MUST be the full 13' section of 105S156 with the swaged end
facing AWAY from the end wall, as installed on page 95.

Slide the plain ends of each drive pipe into
the swaged ends of the installed drive pipe as
shown. If necessary, temporarily tape splices
with 115199 tape until ready to secure with
FA4470B Tek screws.
Once all drive pipes sections are set and measured
correctly, return to each drive pipe splice, untape
(if applicable) and install two FA4470B Tek screws
through the TOP of the pipes.
