ROUND PREMIUM EXTRA TALL HIGH TUNNELS
ANTI-BILLOW ROPE INSTALLATION
TO PREVENT DAMAGE AND POSSIBLE INJURY,
INSTALL THE ANTI-BILLOW ROPES IN SHORT
LENGTHS ALONG EACH SIDE OF THE FRAME.
DO NOT INSTALL AS A SINGLE LENGTH TIED AT
EACH END OF THE BUILDING. DOING SO WILL
RESULT IN A LOOSE SIDE PANEL IF THE SINGLE
ROPE BREAKS DURING STRONG WINDS.

IMPORTANT: IF RIBBON BOARDS ARE USED,
PURCHASE WOOD SCREWS TO ATTACH THE
U-CHANNEL TO THE INSTALLED RIBBON BOARD.
TEK SCREWS ARE NOT WOOD FASTENERS. NEVER
USE TEK SCREWS TO SECURE ANY COMPONENT
TO WOOD. THEY WILL NOT HOLD.

lumber dimensions
shown; wider boards can be used if desired.
BASEBOARDS
The baseboard, when installed properly, helps prevent the
ground posts from sinking into the ground when anchored.
Depending on the building, it also provides a surface to
attach struts or other building components.
ATTENTION:
Baseboards run the frame length along both
sides at ground level. Installation of customer-supplied
baseboard is described later in this guide.
RIBBON BOARDS
A ribbon board typically runs a few feet above the ground
along the sidewall. It serves as a mounting surface for the
u-channel that secures the main cover and roll-up portion
of the main cover. CUSTOMER SUPPLIES FASTENERS
TO SECURE RIBBON BOARD TO RAFTERS. QUARTER
(1/4") CARRIAGE BOLTS ARE RECOMMENDED.
LENGTH DETERMINED BY BOARD THICKNESS.
