3. Locate four (4) QH1070 pipe straps and attach each
strap to the rafter assembly on the underside of the
rafter at each tube joint as shown.
NOTE:
The screws used to secure the pipe straps to the
rafter are also used to secure the joint of the two rafter
tubes. When installing the pipe straps, verify that you are
installing the screws through one pipe and into the
swaged end of the other pipe at the joint.
IMPORTANT:
DO NOT tighten the screws at this time.
These will be tightened after installing the purlins.
