• 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.

  • Measure six radial cords 128 inches including the hooks. You can choose to use knots instead of crimps.

  • Measure one perimeter cord 128 inches to be used between the two front spreaders because they tend to be pulled apart by the wires and need this counter
    pull provided by a cord.

  • Add another short cord about 90 inches between the same two spreaders located in toward the center. Don't use hooks on this short cord; use a cable tie on
    each end to wrap around the spreaders.

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.
Here is how the support cords
are connected to the end of the
spreaders. Just hook down into
the end and then secure the
hook with a large cable tie.

Here is how the cords are arranged on
the spreaders viewing from above.
