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.

Step 2. Assemble the (2) Corner Wind Braces #7 to the 
End Upright w/Foot #3 to the first of the End Arch 
assemblies. Use a #8 Carriage Bolt with Washer and Nut 
to secure the braces loosely to the Upright. Do not tighten 
completely. 
Step 3. Assemble the Interior Arch using (1) Top Crest 
Tube #2, (2) Bent Tube Side Crest #1, and (2) Center 
Straight Upright #4 for the arch. Use #8 carriage bolts with 
washers and nuts in the pre-drilled holes, aligned to form 
the arch. 
Step 4. Support the End Arch with Wind Braces 
temporarily in the vertical position. Connect (4) Swedged 
Cross Rails ‘A’ #5 to the End Arch with (4) Carriage Bolts, 
washers, and nuts through the pre-drilled holes in the arch 
members. The Swedged end of the Cross Rails should 
face the interior of the unit to accept the next cross rail. 
The Cross Rails should be put into the bottom and side 
hole of the arch upright. 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. 
Stand the interior arch assembly up vertically into position, 
so the cross rails align with the holes in the interior arch. 
Using (4) Carriage Bolts #8 with nuts and washers, 
connect the cross rails between the end arch and the first 
interior arch assemblies. Connect the (2) Wind Braces #7 
diagonally across the end and interior arch as shown in the 
frame illustration. 
Step 5. Begin the Top Ridge Rail by placing a Swedged 
Cross Rail underneath the End Top Crest Tube. Secure 
the Cross Rail ‘A’ #5 loosely with a Carriage Bolt #8 with 
washer and nut facing the interior of the unit. 
Step 6. Add the rear end arch in the same fashion. Use 5 
Cross Rail ‘B’ #6 to connect the interior arch and the rear 
end arch as shown in the illustration. Note that the Plain 
end of Swedged Cross Rail should fasten under
 the End 
Top Crest Arch and the Swedged End above
 middle Top 
Crest 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 one person 
lifting each side or corner to avoid bending or stressing 
any frame members. Frame should now be squared up in 
position. Measure from diagonally from inside corner to 
inside corner. Adjust frame and support as necessary to 
bring frame into square. Failure to square frame of unit 
will result in poor cover fit and reduced strength and 
rigidity. If end or interior upright ends are placed on soft 
material that will not support weight, recess small patio 
blocks or bricks under leg ends. This will also allow better 
setting of frame before securing to ground. 
Step 8. Once frame is square and properly supported, 
tighten carriage bolts on all frame members, except for 
End Arch members to Cross Rails along base, side, and 
top. After hardware is tightened, insert plastic end plugs 
#14 (1 5/8”) & #13 (1”) into all open ends of frame 
members.
