4. Place a cross connector (102546) at top of inside rafter, align it with the QH1070 pipe strap attached to underside
of end rafter at the top.
5. Insert
plain end
of purlin pipe (131S075) through cross connector and through
pipe strap at the top of end rafter
.
6. Verify both rafters are plumb and properly spaced (center-to-center) over the top. Verify purlin does not extend
beyond end rafter and tighten cross connector at
top of interior rafter.
7. Return to and tighten the QH1070 pipe strap at top of end rafter to secure purlin. To prevent cover damage, do not
allow purlin to extend beyond outer edge of end rafter. See dashed line—diagram A above.
8. Secure purlin to QH1070 strap by driving a Tek screw through strap and into purlin pipe. See arrow in diagram A.

rafter and repeat Step 10.
12. Install first pipe section of remaining purlins. Consult
diagrams in Quick Start section as needed.
ATTENTION:
To prevent cover damage, DO NOT
