- Support cords from the center post to the ends of the spreaders along with two other cords
between the ends and the middle of the two front spreaders establish and hold the shape of the
hexagonal beam. When installed properly, very little tension is on the wires as these cords do the
physical work
- The cords are made of strong Kevlar with a UV resistant dacron cover and the hardware is
corrosion resistant stainless steel and aluminum crimps.

Finished product
Measure out 7 cords of
Kevlar/Dacron with little "S"
hooks on the end. The
cords should be 128 inches
long, including the hooks.
The Kevlar is very strong
and will not stretch and the
Dacron covering provides
resistance to UV radiation.
Use the crimps instead of
knots.
You will need an
intermediate cord between
the two front spreaders.
Make this cord 89 inches
long but don't use hooks;
instead put a cable tie on
each end that will be used
to wrap around the spreader
at about the 15 M band.

When measuring the cords,
remember that the cords,
although relatively
stretch-free, will stretch a
couple inches under
tension. So pull on them
when measuring and before
crimping them to end up
with 128 inches when
stretched. There is about 7
pounds of force on the
cords when installed on the
beam.
