1. Measure approximately 12"
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.
2. 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
panel components.
The drive pipe mounting clamps
are installed on the underside of the rafters inside the
frame
.
3. Using the 1/4" x 4" carriage bolts and 1/4" nuts,
temporarily secure the 103544 plate to the outside of
the end wall.
4. With the plate in place, mark the location of the 2" drive
pipe hole on the end panel, remove the mounting plate,
and cut the hole for the drive pipe.
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.
5. With the mounting plate attached to the end rafter, take
the 103496 gearbox and place it against the mounting
plate at the desired angle.
6. Using a marker, trace the edges of the gearbox to mark
the desired angle on the mounting plate.
NOTE:
The gearbox can be tilted when mounted to
the plate to allow easier access when using the crank
handle.
7. Set the gearbox aside and remove the mounting plate
from the end rafter
8. Using the diagram below and the marks made in Step
