ASSEMBLING THE FRAME COMPONENTS
After the site is prepared and an inventory of parts is
complete, continue with the rafter assembly.
NOTE:
All rafter assemblies consist of rafter tubes and
purlin clamps. Consult the rafter diagram in the Quick
Start section of these instructions before and during the
rafter assembly process.
Assistance is required to assemble the curved wall frame.
RAFTER ASSEMBLY
Gather the parts:
• Pipe (#22R1901D) (Drilled, Curved)
• Pipe (#26R1901) (Curved)
• Pipe (#26R1902) (Curved)
• End clamps (#102857)
• Band clamps (#QH1404)
• Tek screws (# FA4482B)
• Nut setter 3/8'' x 2-9/16" magnetic
END RAFTER ASSEMBLY
The end rafters include purlin end clamps and band
clamps. Install the purlin end clamps before the different
pipes of the rafters are connected.
The band clamps
for the side struts are installed when the two (2) end
rafters are set into the ground posts.
1. Select the four (4) pipes needed to assemble the first
end rafter and arrange on a level surface.
2. Slide four (4) purlin end clamps and four (4) band
clamps onto the curved pipes in the positions shown.
NOTE:
Position the purlin end clamps with the open
side toward the outside of the building.
3. Use a piece of duct tape to hold the purlin end clamps
and band clamps in position until the rafter is erected.
4. After slipping the clamps onto the rafter pipes, insert
the swaged end of the rafter pipes into the plain ends
of the pipes to assemble the rafter.
5. Once the rafter is assembled, install a Tek screw
through the rafter pipes to secure each joint.
IMPORTANT:
To prevent damage to the cover and end
panels (if equipped), position the Tek screws so the
heads do not contact the cover when it is installed.
6. Repeat steps to assemble the remaining end rafter and
set both end rafters aside.
7. Assemble the interior rafters.
Interior rafters are
assembled exactly the same as end rafters, except
end clamps and band clamps are not used.
8. Continue by assembling the straight wall side rafter
legs.
