Revision date: 11.22.21
ATTENTION:
Install the screws so they will not touch
the cover once it is installed. This is typically on the
backside of the rafter, which will be the surface visible
from the
inside
of the high tunnel once the frame is
assembled.
4. Assemble rafters as described and continue with the
additional steps to complete the assembly of the two
(2) end rafters.
3. With the main rafter pipes seated at each joint and the
rafter positioned on a flat surface, secure each joint
with a single self-tapping Tek screw. Position Tek screw
approximately 2" from pipe joint.
END RAFTER ASSEMBLY
In addition to the steps in the previous procedure, complete
the following steps
for the two (2) end rafters only
.
1. Take one of the assembled rafters and place it on a flat
surface.
2. Slide five (5) end clamps (102857) onto the rafter in the
locations noted below. (Do not secure the clamps to the
rafter at this time. These clamps will be repositioned
during the frame assembly when the purlins are
added.)
NOTE:
Position all clamps as shown. Use a piece of
duct tape (if desired) to keep each clamp from sliding
when the rafter is lifted into position.
View of the end rafter and clamps as shown from the
