GUY ASSEMBLY

Cut four pieces of guy cable 

 (30”) and two pieces 

 (82”). Assemble 

 hex nut

(NO 1) onto each 

 

 (N18). Turn 

 all the way to the eye; as far 

 will go with light pressure

only. These will be used to secure the 

 after guy tensioning.

Install 

 into the top holes of the vertical guy support 

   one eye each direction. Thread

a hex nut about six turns onto each 

Install a egg insulator 

 on one end of each 

 (30”) guy cable and wrap it five or more times.

Take two of these cables and install one on each 

 leaving 

 (12”) between the egg insulator and

the 

 wrap it five or more times and cut off the excess. Take the other two cables with insulators and

wrap each around the boom just in front of the clamp as shown in Figure 4A. Wrap and cut off excess.

Using the remaining two pieces of cable, take one end and thread it through the top egg insulator.

Wrap and cut off excess. Thread the other end through the lower insulator and pull tight enough to remove

slack only. Wrap and cut off excess.

Tension guys by tightening the nuts on the ends of the eyebolts. Secure with the nuts on the opposite

end near the eye.

Line the elements up with the use of a level or any other workable method. Double check the spacing

dimensions and make sure the elements are centered in the boom-to-element clamps. Tighten all hardware
taking care to line the elements up with the use of a level. Check your measurements and make sure the
elements are centered on the boom.
