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.
After reading the MUST READ document and anchoring
the frame, continue by installing the customer-supplied end
frame for the door.
The diagrams shown in the MUST READ document
show frames with mounting feet. The anchor methods
also apply to buildings equipped with ground posts.
