ASSEMBLING THE GOTHIC PRO GREENHOUSE
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 greenhouse frame.
RAFTER ASSEMBLY
Gather the Parts:
• Rafter Pipe (#18G16A)
• Rafter Pipe (#18G16B)
• Rafter Pipe (#166S075)
• End Clamps (#102856)
• Tek Screws (#FA4482B)
• Magnetic nut setter (3/8'' x 2-9/16")
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
onto the ground posts.
1. Select the five (5) pipes needed to assemble the first
end rafter and arrange on a level surface.
2. Slide four (4) end purlin clamps (two on each side of
the peak) over the rafter pipes. Position all end clamps
at the rafter pipe joints. Position the end clamps as
shown.

NOTE:
Position all purlin clamps at the rafter pipe
joints. Consult the Quick Start section for additional
information.
3. After slipping the clamps over the rafter pipes, insert
the swaged end of the rafter pipes into the plain ends
of the pipes to assemble the rafter.
4. Once the rafter is assembled, reposition the purlin
clamps over the pipe joints and 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.
5. Repeat steps for to assemble the remaining end rafter
and set both end rafters aside.
