INTERIOR RAFTER ASSEMBLY
Complete the following steps
for the interior rafters
.
1.
Select the pipes for the first interior rafter assembly and
position these on the ground as shown.
IMPORTANT:
Interior rafters do not use end clamps.
Instead, cross connectors are attached during the
frame assembly.
2. Insert the swaged ends of the rafter pipes into the plain
ends of the pipes and secure each joint with a Tek
screw.
NOTE:
For longer frames, it may be easier to assemble
a few rafters at a time and then begin to assemble the
frame.
3. Once rafters are assembled, assemble the frame.
