Step 5
. Begin the Top Ridge Rail by placing the final
ECR-2031 Plain End Cross Rail underneath the End
Arch Tube. Secure the Cross Rail loosely with a
Carriage Bolt CBN-3000-3 with washer and nut facing
the interior of the unit. This begins the Top Ridge Rail.
The other end of the Cross Rail goes on top of the
Interior Arch as shown in the illustration.
Step 6.
Add the next Interior Arch by placing a
Swedged Cross Rail SCR-2030 into each of the Base,
Side, and Top Ridge Cross Rails, and then attaching
Arch Assembly.
The swedged end of each cross rail slips into the plain
end of the cross rail before it. Secure each Arch
Assembly onto the frame by carriage bolts at each cross
rail. Add all Interior Arches and second End Arch in the
same fashion. Note that the Plain end of the Ridge
Swedged Cross Rail should fasten under the End Top
Crest Arch at the End arch.

NOTE: Do not completely tighten bolts that connect the
Cross Rails to the End Arches. They must be removed
for proper for End Panel Zippered Door installation
Step 7
. Move the frame assembly into its final
installation location. This should be done with at least
two people lifting each arch upright and corner to avoid
bending or stressing any frame members.
Frame
must
then be squared up in position. Use a
straight line string to align all frame members on the first
side into position. Then measure and adjust each arch
base to the proper width of 12’ from side to side. Finally
measure diagonally from inside corner to the opposite
inside corner of frame. Both diagonal measurements
should match. Measure at each end across base of
arches. Do not expand arch width beyond 12’ wide.
This will severely reduce strength of arch assembly and
cause fabric misfit. Adjust frame and support as
necessary to bring frame into square.
Failure to square
frame of unit will result in poor main cover fit and
reduced strength and rigidity
