INSTALL ANTI-BILLOW ROPES
Gather the parts:
• 1/4" Eyebolts and anti-billow rope
• 1/4" nuts and washers
Anti-billow ropes secure the roll-up sides when they are in
the down or closed position. Complete the following steps
to install the ropes.
3. Move up the same end rafter and drill a 5/16" hole
through the poly latch U-Channel and rafter leg, insert
an eyebolt and washer through the hole, and secure
the eyebolt with a nut.
4. Attach the remaining eyebolts using the diagram above
as a pattern guide.
5. Once all eyebolts are installed in the proper locations,
install the anti-billow rope
in short lengths along each
side
. Thread the free end of the rope through the end
rafter eyebolts and the eyebolts at two to three interior
rafters.
6. Cut the rope and tie one end to the eyebolt.
7. Pull the rope tight and tie the remaining end to secure.
8. Repeat the steps to install another section of anti-billow
rope. Continue this pattern until all ropes are tied along
one side and repeat the steps to install the anti-billow
ropes for the remaining side.
NOTE:
The number of individual ropes along any one
side depends on the length of the building and the
length of the rope sections.
9. Check the roll-up side operation.
10. Read the shelter care and maintenance information
that follows.
NOTE:
If the poly latch U-Channel was attached to
a ribbon board (as suggested), the eyebolt can be
mounted through the poly latch channel and ribbon
board to the inside of the rafter.

ATTENTION:
The procedure that follows is applicable
when the frame was constructed using wood boards under
each rafter foot, or if baseboards were installed. If the
shelter was constructed on concrete footings, a concrete
slab, or on bare ground, alternative steps must be taken
by the owner during the following procedure to anchor the
lower ends of the anti-billow ropes.
Additional parts may be
required and must be supplied by the customer.
1. Using the Twist-of-the-Wrist assembly, roll up the
sidewall so that it is a few inches above the ground.
2. Drill a 5/16" hole through the wood baseboard at the
base of the end rafter where the Twist-of-the-Wrist
assembly is located and install the first 1/4" eyebolt and
1/4" washer.
Do not drill through the rafter.
ATTENTION:
If no wood baseboard is present, drill
the hole through the ground post at ground level and
install the eye bolt and washer. Customer-supplied eye
screws can also be used in the baseboard if desired.
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.
