ANTI-BILLOW ROPE INSTALLATION
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.

Ribbon Board
U-Channel
Secure U-channel to
ribbon board using
wood screws.
Ribbon Board
U-Channel
The 102197 U-channel is attached to the sides of the
frame and is used to secure the cover film to the frame.
For best results, attach a ribbon board to the frame and
then secure the U-channel to the ribbon board. All ribbon
board materials and fasteners used to secure the ribbon
board to the frame and the U-channel to the ribbon board
are
supplied by the customer
. They are not included with
this building.
Use of the ribbon board (2" x 4" or 2" x 6") is
optional and left to the customer.
ATTENTION:
If a ribbon board is used, do not use the
FA4482B Tek screws to secure the U-channel to the ribbon
board.
You must use wood screws for this connection.
Install the wood screws every 16" throughout the length of
the frame. The customer supplies the fasteners.
The diagrams that follow show a ribbon board attached to
the frame.
SPLICE U-CHANNEL BETWEEN RAFTERS
If no ribbon board is used, secure the U-channel directly
to the rafters using FA4482B Tek screws. For best results,
cut the first section of U-channel
for the side
to 6' and
secure the splice between the two sections as shown
below. This prevents a seam at a single rafter where two
U-channel sections must be secured to the same rafter.
6" to 8"
6" to 8" splice section installed on
the back side of the U-channel to
the inside of the frame.
