FRAME ASSEMBLY
Gather the parts:
All rafter assemblies
1.315" pre-marked purlins
Cross connectors (#102547)
Tek screws (#FA4482B)
Frame Assembly Procedure:
After all rafters are constructed and placed in an orderly
fashion for frame assembly, proceed with standing the first
end rafter.
Forklifts and personnel booms are recommended for lifting
and setting the rafters. Consult a construction professional
if you are not familiar with construction techniques and
erecting similar structures.
ATTENTION:
Use the proper lifts. Rafter assemblies are
heavy and awkward to handle.
The following photos show
a rafter design may different from actual shelter, photos are
used for illustration purposes only.
With the proper lift, lift the
first end rafter
. This rafter
includes end clamps (installed earlier).

1.
1st Interior Rafter
End Rafter
Anchor the first rafter with ropes or other temporary
bracing.
Verify that the rafter is plumb (straight)
.
2.
NOTE:
In the previous photo, ropes (identified by white
lines for clarity) were used to temporarily anchor the
rafter in place. For this first end rafter, all temporary
bracing
must remain
in place until other rafters are set
in place and attached to the first rafter and to each
other.
Set the second rafter (first inside rafter) in place and
secure it to the rafter feet.
3.
NOTE:
Position someone at each leg to stabilize the
rafter and to keep the rafter from tipping. Additional lifts
or assistants may be needed.
Place a cross-connector (#102547) over the peak of
the inside rafter.
4.
Photo to the right
shows purlin
inserted through
the cross-connector
toward the top of an
interior rafter.
Insert the first section of purlin (1 piece of pipe) through
the cross-connector on the inside rafter and
the end
clamp at the peak of the end rafter
.
5.
IMPORTANT NOTE:
The purlin should extend through
the clamp at the peak of the end rafter but it must not
extend beyond the outside edge of the end rafter, as it
will damage the main cover when the cover is installed.
