FRAME ASSEMBLY
Gather the parts:
• All rafter assemblies
• Pipe 1.315'' x 75'' swaged and pipe 1.315'' x 73.5'' plain
• Band clamps (#QH1400) and cross connectors
(#102547)
• Struts (#QH1308) and Tek screws
Frame Assembly Procedure
1. Stand one end rafter. The end rafters include the end
clamps. Be sure to position the bolt side of end clamp
to the inside of the frame
when setting the rafter in
position. See the diagram below.
NOTE:
Purlin pipe shown in the above diagram is
installed during the frame assembly.
2. Check that the rafter is standing straight (plumb) and
brace it in place.
4. Install the upper two (2) cross connectors on the inside
rafter and insert a purlin pipe through each connector
and through the upper end clamps near the top of the
end rafter. See circles above.
5. Verify that both rafters are plumb and properly spaced
on-center and tighten the upper clamps.
CAUTION:
To prevent cover damage, the ends of the
purlins should extend no more than ½'' past the end
clamp. See diagram that follows Step 1. Do not allow
purlin to extend beyond the edge of the end rafter.
3. Using the on-center, rafter-to-rafter spacing, set an
inside rafter in position. (Additional assistants are
required to hold the inside rafter in position.) See Side
Profile diagrams for the correct rafter spacing.

6. Move to the lower clamp positions and repeat Step 4
to install the purlin pipes in those locations. See the
diagram above.
7. Slide a band clamp (#QH1400) on each of the two
bottom purlins between the second and third rafters.
Position the head of each band clamp bolts toward the
outside of the shelter.
