ROUND ECONOMY HIGH TUNNELS
Revision date: 01.01.20
FINISH ROUGH EDGES
Gather the parts:
• Duct tape (supplied by customer)
• Metal file
1. Check for any sharp edges on the frame and file them
smooth so they will not cut the cover.
2. Apply two layers of heavy duct tape on all pipe
connections and clamps that may contact the cover.
ANCHOR THE ASSEMBLED FRAME
At this point, anchor the high tunnel frame. Consult the
MUST READ document for anchoring information and
suggestions. Please call customer service at 1-800-245-
9881 for additional anchoring information.
CAUTION
: The anchor assembly is an integral part of
the high tunnel construction. Improper anchoring may
cause instability and failure of the structure to perform
as designed. Failing to anchor the shelter properly
will void the manufacturer’s warranty and may cause
serious injury and damage.
4. Use the steps of the previous procedure to install the
top, center purlin.
INSTALL TOP, CENTER PURLIN (continued)
5. Continue with the next procedure.
One pipe of the top, center purlin
installed. Continue by installing
the remaining pipe and clamps.
BASEBOARD INSTALLATION (RECOMMENDED)
Gather the parts:
• Treated or recycled plastic lumber (supplied by
customer).
Recommended: 2" x 6".
• 1/4" x 4" carriage bolts and nuts (may not work for
baseboards with a thickness greater than 1-1/2")
NOTE:
The following procedure describes one way
to install the recommended baseboards. The size
and type of the baseboard you choose may require
the use of alternative steps. When properly installed,
baseboards run the length of the frame.
On the outside of the frame, attach the first baseboard
to the ground posts using the 1/4" x 4" carriage bolts
(FAH009B) and nuts (FALB01B). Continue adding
baseboards to complete the first run. Splices are
made between posts as shown. Use a short section of
baseboard to secure separate baseboards at a splice.
Ground
Level
Inside of
Shelter
Outside of
Shelter
NOTE:
The boards should be at ground level or slightly
into grade to prevent the shelter from sinking and to
create a seal along the bottom. After installing the
baseboards, continue with these instructions.
This baseboard is
not included
with the shipment and must
be supplied by the customer. Treated or recycled plastic
lumber works well for a baseboard.
Recommended dimension: 2" x 6".
