ROUND PREMIUM EXTRA TALL HIGH TUNNELS
END RAFTER ASSEMBLY
Complete the following steps
for the two (2) end rafters
only
.
1. Select the required couplers, clamps and pipes needed
to assemble an end rafter. Arrange these on a flat
surface and assemble rafter as shown below.
2. Position all clamps as shown. (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:
Use a piece of duct tape (if desired) to keep
each clamp from sliding when the rafter is lifted into
position.

outside
when the frame is assembled.
3. With the rafter pipes seated at each joint and the rafter
positioned on a flat surface, secure each joint with a
single self-tapping Tek screw.
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. Repeat the same procedure for the final end rafter.
5. Continue with the
Frame Assembly
