Rafter Assembly
RAFTER ASSEMBLY
After setting the ground posts or anchoring the mounting
feet, continue with the rafter assembly.
NOTE:
All rafter assemblies consist of four rafter sections
joined by a single chevron at the peak. Consult the rafter
diagram in the Quick Start section of these instructions
before and during the rafter assembly process for details.
Assistance is required to assemble the rafters and frame.
Gather the parts:
Rafter sections: See chart below.
•
Rafter chevron (#
• CFG030PINSS03)
1/2" x 3" bolts with nuts (104773), sleeve (110136), and 1/2" flat
•
washers (FAME09B)
Place the rafter sections on the ground end-to-end. Support the

rafter sections with blocks as needed. Consult the diagrams.

2.
the rafter sections using 1/2" x 3" bolts and nuts, 110136 sleeve, and 1/2" flat washers. See
diagram A below and the chart for rafter identification.
Connect the two assembled rafter sections using a chevron, 1/2" x 3" bolts and nuts, and 1/2" flat washers.
3.
Position the installed studs of the chevron so they point up to accept the ridge purlins when these are installed.
See diagram B below.
Distance between the lower mounting holes at the end of the assembled rafter is the
on-center width of the frame. Measure this distance before you tighten the bolts at the top of the rafter. For
example if your frame is 35' wide on-center, the distance between the mounting holes is 35' on-center.
For long frames, it may be best to assemble the individual rafters and set them in place to conserve work space. To
reduce handling, designate assembly areas along the length of the frame and set the individual rafter sections in
those areas to be assembled and connected to the frame.
After assembling some or all of the rafters, continue with the frame assembly.
