Assembly Instructions
14X30X12 Round Utility
should be planned so that it does not run into the unit.
As well, rain or melting snow that comes off the unit
should be drained away rather than accumulate and pool
around the unit.
Check to be certain that adequate clearance is allowed
for entry and exit from ends of unit. As unit has doors on
both ends, ideally boat or equipment can be inserted or
removed from either end.

FRAME ASSEMBLY
Step1.
Arch Assembly – Begin arch assembly by
attaching four MC-9000 Mid Connect Tubes to four End
Upright with Foot (EUL-5021). Slip the swedged end of
the upright leg into the plain end of the Mid Connect
Tube. Use a 2 1/8” (CBN-3005-2) Carriage Bolt with Nut
and curved washer to secure the parts together. Next
assemble the remaining 10 Mid Connect Tubes (MC-
9000) to each of the remaining 10 Center Straight
Uprights (CSU-5020). Use a 3¼” (CBN-3005-3)
Carriage Bolt, Nut and Cupped Washer for each. Do not
tighten hardware.
Next assemble each of the Right Side Crest Tubes (RC-
5020) to Left Side Crest Tubes (LC-5021). Slip the
swedged end of the Right Crest Tube into the plain end
of the Left Crest Tube together. Use 3¼” (CBN-3005-3)
carriage bolts with nut and washer through pre-drilled
holes in frame members. A total of seven pairs will be
assembled.
Be certain to insert carriage bolts from the outer edge
into the interior of the unit, with the washers and nuts on
the inside of the arches. This will avoid tearing the fabric
on doors and main cover when installed. Do not tighten
the nuts completely until the frame is completed and set
in place.
Attach one end upright/mid tube connect sub assembly
to each end of a pair to assembled crest tubes to
construct each end arch (Qty - 2). Attach one Center
Upright/Mid Connect Tube sub-assembly to each side of
the remaining Crest Tube pairs to construct the interior
arches (Qty - 5).
Step 2
. Assemble each of four (4) Corner Wind Braces
from section A & B with 1¾” (CBN-3005-1) Carriage
bolts & nuts. Assemble two (2) Corner Wind Braces
(CW-2800) to the first End Arch Assembly to the lower
hole on Upright w/ Foot EUL-5021 (refer to frame
illustration). Use a 3¼” (CBN-3005-3) Carriage Bolt with
Washer and Nut to secure the braces loosely to the
Upright. Do not tighten completely.
Step 3
. Prepare the first End Arch Assembly by
attaching the first of the side and cross rails. Begin the
bottom and side rails with (4) (ECR-5031) Plain End
Cross Rails to the End Arch with 3¼” (CBN-3000-3)
carriage bolts, washers, and nuts through the pre-drilled
holes in the arch members. The Cross Rails must be on
the interior of the arch assemblies. The Base Cross
Rails should be put into the bottom hole of the arch
upright. The Side Cross Rails should be placed in the
top hole of the Mid Connect Tube where it meets the top
crest tube. Again, don’t tighten the hardware until the
next arch and cross rails are assembled. It is very
important to make certain all nuts are on the inside of the
unit to avoid damaging the cover when put on.

With the assistance of a second person, support the End
Arch Assembly vertically. Next stand an interior arch
assembly up vertically into position, approximately 60”
apart. Connect the Base and Side Cross Rails from the
End Arch to the Interior Arch. Align the holes near the
end of the cross rails with the holes in the interior arch.
