SITE PREPARATION
Select a level or as close to level as practical location for 
your Rhino Shelter unit. The unit should be placed on a 
base of materials suitable for the storage load to be 
protected. The unit should not be located under trees, 
which will shed hard fruit such as apples, walnuts, or 
heavy pine cones. The cover of your unit will protect 
against normally leaves and light debris, however large 
branches or other falling items may cause puncture or 
tears in the cover material. 
 
Take notice of drainage around your intended location. 
Water draining from the surrounding terrain 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 vehicle or equipment can be inserted 
or removed from either end. 
FRAME ASSEMBLY 
 
Step1. Assemble the two End Arch Assemblies. Each 
consists of (1) Right Side Crest Tube RC-3020, (1) Left 
Side Crest Tube LC-3021 and (2) End Upright w/Foot 
EUL-4021 for each one. Assemble as shown below. 
The swedged ends slip into the plain end pipe of the 
adjoining frame member. Use (4) CBN-3005-3 carriage 
bolts with nuts and curved washers through pre-drilled 
holes in frame members. 
 
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. Attach the (2) Corner Wind Braces CW-1800 
(flattened ends) to the End Upright w/Foot EUL-4021 to 
the first of the End Arch assemblies. Use a CBN-3005-2 
Carriage Bolt with Washer and Nut to secure the braces 
loosely to the Upright, into the hole just below the side 
cross rail. Do not tighten completely. 
 
Step 3. Assemble the Five Interior Arch Assemblies 
using (1) Right Crest Tube RC-3020, (1) Left Crest Tube 
LC-3021, and (2) Center Straight Upright CSU-4020 for 
each. Use CBN-3000-3 carriage bolts with washers and 
nuts in the pre-drilled holes, aligned to form each arch. 
Place aside for the moment. 
 
Step 4. Support an End Arch with Wind Braces CW-
1800 temporarily in the vertical position. Connect (4) 
ECR-2031 Plain End Cross Rails to the inside of the End 
Arch onto the (4) CBN-3005-3 carriage bolts that 
assembled the interior arch members. The Cross Rails 
should be put into the bottom and side hole of each arch 
upright. These will begin the Base Cross Rails and Side 
Cross Rails on each side of the frame assembly. Again, 
don’t tighten the hardware until the next arch and cross 
rails are assembled. 
 
Step 5. Stand an Interior Arch Assembly up vertically 
approximately 48” from the End Arch Assembly with 
cross rails. Align the cross rails from the End Arch with 
the carriage bolt holes in the Interior Arch. Remove the 
(4) nuts and washers on the carriage bolts, and connect 
the cross rails between the End Arch and the first Interior 
Arch. Connect the (2) Wind Braces #CW-2005 
diagonally across the end and interior arch as shown in 
the frame illustration.
