CHAPTER TWELVE
SECTION 12.1
40/30 ELEMENT TRUSS KIT (continued)
ATTACH THE TRUSS COUPLERS
There are two pieces to the truss couplers (PN 10-1510-01) as shown in
figure 12.10
. The couplers are
mounted on each side of the loop, located at the outer joint of the telescoping poles as shown in
figure
12.11
. The truss coupler butts up against the edge of the polyolefin heat shrink.
There are nut trays molded on one side of the truss coupler as shown in
figure 12.12
. These are handy for
holding the #6 Nylock nut (PN 60-0014) when tightening, but you will need to position your finger over the
nut to keep it from spinning when you thread on each of the #6 x 7/8” pan-head machine screw (PN 60-
0014-01) as shown in
figure 12.13
. Only the outer four holes of the truss coupler are used for attaching it as
shown in
figure 12.14
. Note that the top portion of the coupler (the portion facing skyward) has a hole, but
this is also not used as shown in the second picture of
figure 12.14
. Align the truss coupler so that it is paral-
lel to the telescoping pole and tighten each nut.
The Dacron truss cord is provided in a single piece and will need to be trimmed as you progress with the in-
stallation of the end trusses. Thread the Dacron cord through the truss coupler, leaving approximately ten
inches of truss cord as shown in
figure 12.15
. Tie four half-hitches and leave approximately four inches of
leader as shown in
figure 12.16
.
Figure 12.17
shows the proper way to tie a half-hitch. When finished, apply
electrical tape so that the leader of the Dacron rope is secured to the truss line as shown in
figure 12.18
.
