FRAME CHECK
Before you attach the side panels, inspect the frame for
sharp edges or fasteners that could damage the panel or kit
components.
1. Verify that all frame members are properly secured.
2. Verify that all bolts and clamps are tight.
3. Recheck the frame assembly for sharp edges or
clamps and bolts that may interfere with the installation
of the panel. File or tape sharp edges as needed.
4. Reposition clamps and bolts as needed and tape all
rafter pipe joints with duct tape to protect the panel.
5. Verify that the main building frame is properly and
adequately anchored.
Do not attach the side panels to an unanchored frame.
6. Continue by installing the side panels and components.
INSTALL THE DROP-DOWN SIDES
If your building includes roll-up sides, go to and complete
the
"Install Roll-Up Sides"
procedure.
Do not continue
with these drop-down panel steps.
Locate these parts to attach the pulleys and drop-down
panel drive pipe:
• 131S075 (1.315 swaged pipe for drive pipe) and
131P0XX (where XX represents the length needed to
complete the drive pipe assembly). See side profile for
pipe identification if needed.
• 106734 band clamp
• 103496 gearbox and 103544 mounting plate
• 102717 double drive
• FA4482B Tek screws (for drive pipe)
• FAH009B (1/4" x 4" carriage bolts) and FALB01B (1/4"
nuts)—use with FAME50B flat washers on the nut side.
• FAH005B (1/4" x 2" hex head bolts)
• FALF15B (1/4" lock nut) and FAME50B (1/4" flat
washer)—used to secure the mounting plate.
Continue with the steps that follow to install the drop-down
panel components.
Take the 103544 mounting plate (shown below) and
move outside the end wall where you want to position
the gearbox.

ATTENTION:
Depending on the mounting plate design,
it may be necessary to redrill and reposition the plate
mounting holes to keep the drive pipe closer to the
rafters.See the diagram below for an example.
May not apply to all drop-down sides and mounting
plates.

End Panel
Drill new mounting
holes to position
gearbox closer to
rafter.
After installation
and confirming
that the drop-down
panel operates
as needed, cut
mounting plate
even with rafter to
prevent damage
and injury. See
dashed line above.
Position bracket
so large drive pipe
hole is close to
rafter pipe.
