FRAME ASSEMBLY (continued)

8. Move to the side clamp positions and repeat steps to
install the first purlin pipe in those locations.
#102547
IMPORTANT:
The side purlins are located just
below the "V" and are installed using 102547 cross
connectors.
9. Continue adding rafters and purlin pipe until the frame
is assembled. Secure all purlin splices using Tek
screws. See Step 10.
NOTE:
Each purlin assembly consists of 1.315'' x 75''
(#131S075) swaged pipes (number is determined by
shelter length) and one (1) 1.315'' x 73.5'' (#131P0735)
plain pipe.
10. Finish each purlin run using the plain, shorter pipe
(#131P0735), and use the final end rafter to complete
the assembly.
NOTE:
If the last end rafter is plumb and the purlin
run extends beyond the end of the rafter, cut the last
section of purlin pipe to the required length.
Typically purlin pipes
do not
require cutting.
Verify that
you have the correct plain pipes before you decide to
cut any pipe to complete the purlin runs.
CAUTION:
To prevent cover damage, the ends of the
purlins should extend no more than ½'' past the end
clamp. Position the bolt side of the end clamps toward
the “inside'' of the shelter (the same side as the purlin).
11. Once all rafters are set and all purlins are in place and
secured, return to each pipe splice of each purlin run
and install a Tek screw through the pipes to secure the
joints if this was not completed during assembly.
12. Return to each end clamp and cross connector, and
secure to rafters and purlins using Tek screws.
