INSTALL ANTI-BILLOW ROPES
Gather the Parts:
• Eye Screws and Eyebolts
• Anti-Billow Rope
• Nut and Washers
Anti-billow ropes secure the roll-up sides when they are in
the down position. Complete the following steps to install
the ropes.
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. Install the first eye screw into the wood baseboard at
the base of the end rafter where the Twist-of-the-Wrist
assembly is located.
ATTENTION:
If no wood baseboard is present as
required, additional steps must be take to anchor
the lower portion of the anti-billow ropes. (Contact
Customer Service at 1-800-245-9881 to purchase
additional parts if needed.)
3. Move up the same end rafter and drill a 3/8" hole
through the poly latch U-Channel and rafter leg, insert
an eyebolt through the hole, and secure the eyebolt
with a nut and washer.
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.
4. Attach the remaining eye screws and eyebolts using
the diagram below as a pattern guide.
5. Once all eyebolts and eye screws 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/eye screws and
the eyebolts/eye screws at two to three interior rafters.
6. Cut the rope and tie one end to the eyebolt/eye screw.
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, rafter
spacing, and the length of the rope sections.
9. Check the roll-up side operation. Adjust rope tension as
needed.
10. Read the Shelter Care and Maintenance information
that follows.
