end rafter, secure the 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)
Once all rafters are set and all purlins are in place and

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.
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.
Splices are made between posts as shown. Use a short
section of baseboard to secure separate baseboards at a
splice.
If the recommended baseboard (customer-supplied) is not
used, secure the required diagonal struts to the ground
post using a Tek screw or other customer-supplied fastener.
The installation of the diagonal struts is described as
follows.
