RAFTER ASSEMBLY (CONTINUED)
6. Adjust the leg and plain pipe to be at a 90 degree angle
and attach a strut to the band clamps as shown below.
7. Repeat the steps to construct the remaining rafter
assemblies.
FRAME ASSEMBLY
Connect the rafters using the remaining 20' purlin
assemblies and struts.
Gather the parts:
• Rafter assemblies
• 20' purlin assemblies
• 3/8'' x 1'' cap screws (#FAG355B)
• Strut (#103838) and band clamp (#103856)
Complete these steps:
1. With assistance, stand the first rafter assembly and
hold or brace the assembly in place. If ground posts are
used, set the rafter assembly in position on the ground
post and secure each leg to the ground post.
NOTE:
Before securing the rafter legs to the ground
posts (if used), refer to the diagram for your shelter in
the Quick Start section to determine where to attach
the diagonal struts. Slide additional band clamps onto
the legs of each rafter assembly as needed.
2. Position a second rafter assembly (as shown) and
brace or secure it in place at approximately 20' from the
first rafter.
5. Use the diagrams above and in the Quick Start section
and repeat the above steps as needed to assemble the
remainder of the frame.
3. Slide a band clamp onto each end of two (2) 20' purlin
assemblies and insert the ends of each purlin into
the cross ports of the 5-way couplers of each rafter
assembly.
4. Thread the 3/8'' x 1'' cap screws into the holes of the
couplers, verify that the on-center length dimension
is 20' 3", and tighten the bolts to secure the purlins in
place.
