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.

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.

Interior Arches
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.

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. Support End Arch feet with patio blocks or bricks as
needed if ground is soft and will not support weight. After
hardware is tightened, insert plastic end plugs EP-1000
(1 5/8”) & EP-1001 (1”) into all open ends of frame
members.
ANCHORING FRAME TO GROUND
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.
Do not over tighten or oval tubing. After hardware is
tightened, insert plastic end plugs #14 (2 3/8”) & #15 (1
1/8”) into all open ends of frame members.
NOTE: Frame must be anchored before
installing any doors or cover.
Each Rhino Shelter 12x24x12 greenhouse comes with
12 EARTH CABLE ANCHORS with U-bolts and nuts.
These versatile anchors allow the frame to be secured to
almost any surface. In addition you have also been
provided with a 36” Drive Rod used to drive the anchor
heads into the earth.
If the location where you are placing the building has
very hard ground or any rock in it, pre-drill the holes
before inserting anchors. Hammer drills can be rented
at most home improvement or rent-all centers. Hitting
the anchors into rock will cause the drive rod end to
mushroom inside the anchor head, and prevent the drive
rod from coming out of the hole.
Anchor placement should be made inside the frame at
the interior corners of the unit, and midway along the
sides of the frames. Anchors secure the building to the
ground, as well as prevent spread of the frame over
time.

Step 1. Place the drive rod provided into the cup of the
anchor. Using a heavy hammer drive the anchor into the
soil until 6-8 inches of cable remains above the earth.
Remove drive rod.
ANCHOR STEP 2
Place the Drive Rod through the loop in the anchor
lanyard. Pull upward to set anchor head into the ground.
ANCHOR STEP 3
Slip one side of the U-bolt through the eyelet at the end
of the anchor cable. Attach the cable to the Arch leg
upright with the U-bolt and tighten. Do not attach to base
cross rails. Ensure there is no slack in the cable. Slack
can be removed by wrapping the cable around the tie-
down rail.
END PANEL INSTALLATION
Note: End panels MUST be installed before installing
Main Cover onto frame.
Step1. Remove Carriage bolts from the Top Crest Rail
and the two Upper Cross Rails. Install one End Panel
Door w/Zippers DZD-5002 at a time to the Frame
assembly. Carefully align the door material over the
arch to make an even fit.
Step 2. Place the end panel over the first arch and wrap
the material over the End Arch bringing the slits in the
end panel to the inside of the frame. End Door Panels
have pre-cut slots that allow frame members to pass
through so rope pocket is inside unit. Place the top ridge
rail pole and the side cross rail poles through the
material slits and replace the carriage bolts and tighten.
Each door end will also require removal of the wind
brace bolts and placement of the wind braces through
slits in the ends panel. Reconnect wind braces with
carriage bolts once end panel is put into place.

The rope slot should be located inside the unit, with the
frame members passing through the pre-cut slots in the
end panel/door. Replace the carriage bolts after putting
the end panels into position.
When putting on the doors, adjust the length to make
certain the doors do not drape onto the ground. If pulling
them up puts too much stress on the slit where it goes
over the wind brace, use a sharp knife to cut slit another
inch or two to relieve it. The PE fabric is rip-stop weave,
and can easily be cut to relieve stress at the frame
members.
Step 3. Tie off one end of the rope coming out of the
end panel to a turnbuckle (turn-buckle should be
loosened all the way) and attach the turnbuckle to the
hole in the foot of the end arch. Hold the end of the
unsecured rope and apply downward pressure with a
foot to remove excess slack.
Re-adjust gathered material evenly along inside edge of
door rope slot. This step is key to getting a good door fit.
Tie off the end off the rope to a second turnbuckle (fully
opened) attached to a hole in the foot of the end arch on
the opposite side. The end panel can then be tightened
further by adjusting each turnbuckle.

Note: Adjust the end door panel by turning the
turnbuckles or repeating step 3 on a regular
basis
MAIN COVER INSTALLATION
Step 1. To elongate the life of Main Cover, put a small
square of duct tape (field supplied) over each bolt head
on frame that comes in contact with cover. The tape
acts as a cushion to avoid rubbing damage to the cover
over years.
After covering bolt heads with tape, unpack the Main
Cover #RUC-10000 from the protective plastic
packaging. The line of grommets on the inside (white) of
the cover on the tie Down Flap run parallel to the sides
of the frame assembly for positioning. Once cover is
oriented properly to the Frame Assembly, pull Main
Cover over top of frame assembly from the side, being
careful not to snag the cover on any member, bolt, or
other obstruction. Center the Main Cover over the
Frame Assembly with the Main Cover colored side
showing from the outside of the unit.
Step 2. Loosen the 4 remaining turnbuckles completely.
Place the turnbuckles into hole in the foot of the end
arches on the outside of the end panel. Tie off the rope
coming out of the Main Cover rope slot on either side to
the turnbuckles. After tying off one end of the rope in the
Main Cover, pull the excess slack out of the rope and
cover. Hold the end of the rope and push directly down
with a foot onto the excess rope.
Temporarily tie the other end of the rope to the
turnbuckle. Go over the entire edge of the cover and
adjust the excess folds of material around the end so it is
evenly distributed around rope slot. Once the rope is
pulled tight and the cover is adjusted evenly over frame,
tie off the rope end to the turnbuckle. All slack should be
out of the rope at this time. Tighten the turnbuckle to
further tighten the cover if necessary. Ensure the cover
is centered. (this step may need to be repeated to
ensure a snug and centered fit)
Step 3. When the cover is completely aligned secure
each side of the cover to the bottom cross rail using the
ropes provided. Start at one end and tie off the rope to
the cross rail. Lace the rope through the grommets in
the cover and back under the tie-down cross rail.
Repeat this on the opposite side. Cover edge flap
should be on the outside of unit to repel rain or snow.
Pay close attention to how tight the cover is put onto the
frame. It should be tight enough so it does not flap
around in the wind, but not so tight that it tears the
material cover. The fabric backed PE fabric of Rhino
Shelter units does not stretch. If you pull it so tight that
the fabric is stretched, a small amount of additional
stress from wind or contact can cause premature tears
and failure. Only tighten cover enough to remove
valleys between arch assemblies. Do Not over tighten.

MAINTENANCE AND CARE
Step 4. Retighten or readjust the turnbuckles on both
the cover and end panels as needed. Retighten the
rope holding the main cover to the bottom cross rail.
Both the cover and the end panels should be
checked and tightened on a monthly basis.
DOOR HOLD UPS
All Rhino Shelter doors are manufactured with a pocket
on the bottom edge along the width axis. A ½” - 1”
plastic or metal tube can be inserted into the pocket and
trimmed to fit door width. Weight will reduce door
movement in wind. Four (4) bungee straps are provided
to retain the door in the up position. Roll the door from
the bottom and secure the door roll with a bungee
through the upper door grommet as shown.
Annually or more often, the unit should be completely
inspected internally and externally to make certain the
unit remains properly installed and secured. Particular
attention should be paid to:
Hardware – check all carriage bolts and hardware
connectors to be certain they are in place and tightened.
Anchors – during normal weather trends, the unit will
strain against the anchors under windy conditions.
Anchor hardware connection to frame members should
be maintained tight and depth of anchors should be
checked to be certain they remain deeply and firmly set.
Snow Accumulation – all snow accumulation on the main
cover should be removed as soon as practical. The
days following a snowfall when snow melts are when the
most damage can occur. Unit is not designed for any
amount of accumulated snow or ice. Tap the main cover
from the inside with a broom end to knock off any
accumulated snow.
Main Cover Lacing – the poly rope that secures the main
cover to the bottom rail of the frame assembly should be
checked, and adjusted as needed. The tension on the
main cover should be uniform from end to end and side
to side. Rope ends must be tied off onto the frame
members at the ends on each side.
Turnbuckle Adjustment – during normal wind conditions
and load, the doors and main cover adjustment points at
the turnbuckle should be checked and tightened as
necessary. The turnbuckles should be neither
completely extended nor taken up, so that turnbuckle
should be tight when in the mid range of overall
adjustment. If necessary, readjust rope tie off on
turnbuckle as needed to tighten or loosen as needed.
Cleaning – cover and doors can be cleaned with a
mixture of light detergent and water. A soft bristle brush
with the mixture can be used to loosen any hard dirt,
mold, or buildup on the cover. After cleansing, the cover
should be rinsed thoroughly to avoid any chemical
reaction from residual detergent. Allowing dirt and
debris to sit on cover over an extended time will damage
cover irreparably.
Severe Weather – in preparation for inclement weather,
completely secure the doors on both ends of your Rhino
Shelter greenhouse. Allowing wind to enter either end
lifts the building and puts undue stress on the anchoring
system. This also shortens the life of the doors, zippers,
and main cover.
