FRAME ASSEMBLY
Gather the parts:
• All rafter assemblies
• Purlin pipe 1.315" x 75" swaged (131S075)
• Purlin pipe 1.315" x 45.5" plain (131P0455)
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.
NOTE:
Plumbing the end rafter at this stage assists in
placing the remaining rafters.
2. Position rafters to maintain width at 34' on-center.
3. Secure the rafter feet to the site (or customer-supplied
baseboards) to prevent the rafter from shifting.

Assemble Interior Rafters Without Attached Ratchets
1. Select the rafter pipes (see End Rafter Assembly)
and assemble and secure the pipes as previously
described.
2. After securing each pipe joint using one self-tapping
Tek screw, attach rafter foot (104302) to the rafter using
the 3/8" hex head bolt (FAG363) and nut (FALB04B).
INTERIOR RAFTER ASSEMBLIES (CONTINUED)
3. Repeat Step 2 to attach the remaining rafter foot.
4. Repeat the above procedure to assemble the
remaining interior rafters without ratchets.
5. Place all interior rafters without attached ratchets in a
pile separate from either of the other rafter piles.
NOTE:
You must be able to access all three rafter piles
easily throughout the assembly steps.
Bolt head to the
outside of the
shelter.

1. Stand the first end rafter and secure it using rope,
cable, or some other form of temporary bracing to hold
the rafter in position. Use a level (or other leveling
device) to plumb the end rafter.
NOTE:
The use of a baseboard beneath the feet of the
rafters is strongly recommended. The feet then can be
secured to the baseboard using the customer-supplied
lag screws or other appropriate fasteners.
If used, baseboards should be "pinned" in place to
prevent them from moving during assembly.
Anchoring
the rafter feet to customer-supplied baseboards is not a
substitute for anchoring the frame to the site
.
Consult the MUST READ documentation that shipped
with the building for anchoring instructions.
Baseboards can be treated wood or recycled plastic
lumber. Contact Customer Service at 1.800.245.9881
for additional information.
