INSTALL THE DROP-DOWN CURTAIN
Locate these parts to attach the pulleys and drop-down
curtain axle:
• 131S075 (1.315 swaged pipe for axle) and 131P0XX
(where XX represents the length needed to complete
the axle assembly). The axle consists of the same pipe
as the purlins. See side profile for pipe identification if
needed.
• 106734 band clamp
• 103496 gearbox and 103544 mounting plate
• 102717 double drive
• FA4482B Tek screws (for axle conduit)
• FAH009B (1/4" x 4" carriage bolts)
• FAH005B (1/4" x 2" carriage bolts)
• FALF15B (1/4" lock nut) and FAME50B (1/4" flat
washer)
Continue with the steps that follow to install the drop-down
curtain components.
1. Take the 103544 mounting plate (shown above) and
move outside the end wall where you want to position
the gearbox.
2. Measure 12" to 24"
above the ribbon board
along the
end rafter, place the mounting plate against the end
wall, and align the plate mounting holes with the center
of the end rafter.
3. Mark plate mounting hole locations and drill the holes.
Use a 1/4" drill bit for the mounting holes.

NOTE:
Do not position the mounting plate in a location
where purlins, clamps, or other frame components will
interfere with the installation of the drop-down curtain
components.
The axle mounting clamps are installed
on the underside of the rafters inside the frame
.
4. Using the 1/4" x 4" carriage bolts and 1/4" nuts,
temporarily secure the 103544 plate to the outside of
the end wall.
5. With the plate in place, mark the location of the 2" axle
hole on the end wall polycarbonate panel, remove the
mounting plate, and cut the hole for the axle conduit.
NOTE
: If the end wall is covered with a fabric panel,
use a utility knife to cut a small X through the panel
within the 2" hole position and continue.
