FRAME ASSEMBLY (CONTINUED)
10. Continue adding rafters and purlins until the frame is
assembled. (Remember to slide a band clamp onto
each bottom purlin between the second and third
rafters at the remaining end of the shelter.)
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 XX" (#131P0XX)
plain pipe. The XX" represents the remaining length
needed to reach the end of the frame. Consult the
Spec Sheet for part identification.
11. Finish each purlin run using the plain, shorter pipe
(#131P0XX), 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 the
finished purlin run has the correct plain pipe before
cutting any pipe.
MOUNTING BOARD INSTALLATION
The mounting board is supplied by the customer. For this
example, it is attached
above the bottom purlin
along both
sides of the frame
on the inside of the frame.
Consult the
diagrams in the Quick Start section to view the mounting
board installed below the lower purlin.
ATTENTION:
Use the pivot wheel assembly to measure
the required height of the mounting board.
Building frame
must rest on all rafter legs when the wheel assemblies are
in the retracted position.
Gather the parts: (All mounting boards and fasteners are
supplied by customer.)
• 2" x 6" (or larger) boards at required length
• Fasteners to secure mounting boards to frame
• 1/4" x 4" carriage bolts and 1/4" nuts
1. Measure the board height needed using the wheel
assembly in the retracted position and mark the
locations on the rafter legs.
NOTE:
Building frame must rest on all rafter legs when
the wheel assemblies are in the retracted position.
On the inside of the frame, attach the first board to the
end rafter
using two (2) carriage bolts and hex nuts.
NOTE:
DO NOT allow the mounting boards to extend
beyond the end rafter. Boards must be flush with end
rafter.
View shows the frame from the outside.

The diagram below shows the mounting board installed
above the lower purlin. Consult the diagrams in the Quick
Start Guide to view the mounting board installed below the
lower purlin.
Either application is acceptable.
Consider the
building use when attaching the mounting boards.
NOTE:
To prevent cover damage, DO NOT allow the
purlin to extend beyond the end rafter.
12. Return to each clamp and install a Tek screw through
the clamp and into the purlin pipe as shown.
13. Secure each clamp to the rafter using a Tek screw.
