4. The Dacron rope is provided in a single piece. You will need to trim the pieces to length as you proceed in
installing each half-portion of the truss. Melt the end of the rope with a lighter as shown in figure 2.09
to insure it does not fray. Thread the Dacron rope through the single larger hole at the top portion of the
coupler as shown in figure 2.06, so it is tight and the elements are level, with the turnbuckle approxi-
mately half way unscrewed. This should let approximately 10” of rope stick out the other end. Secure the
rope to the coupler using four half-hitches, leaving approximately 4” extra rope or leader”. Run the rope
up the telescoping pole towards the stainless steel eye-bolt/thimble and then thread the rope through the
thimble and back down to the truss coupler opposite of the one that is already secured. Figure 2.07
shows the Dacron rope tied to the element truss coupler.
5. Tape the leader
to the main
truss line as shown
in fig- ure 2.08,
trim the rope for
that por- tion of the
truss and re-
peat for the next.
There will be
more than enough rope. Tape the leader to the other portion of the rope as
shown in figure 2.08. Electrical tape works fine for this.
6. Melt the other end of the rope with a lighter as shown in figure 2.09 to insure it does not fray. Figure
2.10 shows the finished coupler with the Dacron rope secured.
