Secure the rafter legs to the ground posts as previously
described and steady the rafter.
NOTE:
Insert a tapered pry bar into the bolt holes of
the ground posts and twist the ground post to align the
holes with the rafter bolt holes if needed.
Remove another section of purlin pipe from each pre-
marked purlin assembly and attach these to the rafter.
Verify that the distance between the rafters is 48"
center-to-center.
Adjust the rafter forward or backward
as needed to maintain this dimension.
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.
Attach and secure the remaining 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, verify that the
correct pipe was used, and cut the last section of purlin
pipe to the required length.

FRAME ASSEMBLY (CONTINUED)
Dashed line shows
ground level.
Frame length may differ from actual frame.
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.
Remove any temporary bracing (if needed) and install
the baseboards (recommended) and the side struts.

BASEBOARD INSTALLATION (RECOMMENDED)
The baseboard (strongly recommended) is supplied by the
customer and is attached at ground level along both sides
of the frame. It helps keep the ground posts in place and
also prevents the frame from working into the ground when
anchored.
Continue with the strut installation if baseboards
are not used.
Attach the baseboards to the frame on the outside of the
ground posts at this time.
Gather the parts:
Treated or recycled plastic lumber (supplied by
customer)
1/4" x 4" carriage bolts and 1/4" nuts
NOTE:
The following procedure describes one way to
install the recommended baseboards. The size and
type of the baseboard chosen may require the use of
alternative steps. When properly installed, baseboards
run the length of the frame.

NOTE:
The boards should be at ground level or slightly
into grade to prevent the shelter from sinking and to
create a seal along the bottom.
After installing the baseboards, continue with these
instructions.

On the outside of the frame, attach the first baseboard to
the ground posts using the 1/4" x 4" carriage bolts and
nuts. Continue adding baseboards to complete the first
run. Use a short section of baseboard to secure separate
baseboards at a splice between posts. Fasteners and
splice materials are supplied by the customer.
