FLEX ZONES
Flex zones are formed in the area around the tops and bottoms of the posts to prevent a concentration of forces
in these places.
In these flex zones, the mesh is not directly attached to the support ropes. Instead, 2 helix springs are wound be-
tween the mesh and support ropes.
For a length of 1.75 m or 0.875 m, the helix 3500 x 64/4 - 90 is cut in half or quarters on site.
Flex zones for middle posts
In the area of the 10 diamonds 206 , the first helix 304.1 is wound into the upper support rope. The second helix
304.2 is wound into the mesh and the first helix.
207 : The helix 304.1 is not wound into the support rope between the two shackles that the upper support
rope is routed through
The topmost and the third topmost diamond of the adjacent meshes are also each connected with a 3/8" shackle
80 in addition to the helix.
