18. Secure the purlin pipe joint with a Tek screw.
Repeat the above steps as needed to stand and secure
the remaining interior rafters and purlins to complete
the frame assembly.
IMPORTANT:
Verify that you have slipped a band
clamp onto each leg of the
end rafters
and the
first
interior rafters
at each end.
19. Secure the end rafter to the ground posts, and
attach the purlins to it. Verify that the end clamps are
positioned with the nut and bolt to the inside of the
assembled frame. Refer to the Quick Start section and
previous diagrams if needed.
NOTE:
If the last end rafter is plumb and the purlin
extends beyond the end of the rafter, cut the last
section of purlin pipe to the required length.
FRAME ASSEMBLY (continued)

Frame shown may differ slightly from actual frame.
20. Once all rafters are set and all purlins are in place and
secure, return to each pipe splice of each purlin and
verify that a Tek screw is installed. Install a Tek screw if
needed.
21. Remove any temporary bracing (if needed), read the
following information, and install side struts.
ANCHOR THE ASSEMBLED FRAME
At this point, anchor the greenhouse frame. Consult the
MUST READ document for anchoring information and
suggestions. Please call customer service at 1-800-245-
9881 for additional anchoring information.
CAUTION
: The anchor assembly is an integral part of
the greenhouse construction. Improper anchoring may
cause instability and failure of the structure to perform
as designed. Failing to anchor the shelter properly
will void the manufacturer’s warranty and may cause
serious injury and damage.
SIDE STRUT INSTALLATION
There are four (4) side struts (#QH1304) for shelter. Struts
are positioned at first rafter space at each end.
Gather parts:
• 5' Struts (#QH1304)
• Short Tek screws (#FA4482B)
NOTE:
Heads of bolts on band clamps to face toward
outside of shelter.
