3.4. INSTALL TRUSS CABLES
See Figure 3.25 for details (X160-85 shown, other models are similar).
1. Attach eyebolts (1) to both ends of a truss cable (3) with two 1/2” cable
clamps (2), using about 10” (25.4 cm) to 12” (30.5 cm) of cable. Tighten
securely.
2. Thread the cable through the cable return bracket (4) on the underside of the
lower tube, and pull the cable through until there is an equal length of cable
on each side of the tube. Secure the cable to the cable return bracket with a
1/2” cable clamp (5), ensuring that the cable clamp is loose enough that the
cable remains free to move.
3. Insert the cable eyebolts into separate turnbuckle bodies (6) and secure with
3/4” locknuts threaded fully onto the eyebolt shaft, but not further than 1/4”.
4. Attach eyebolts (1) to the unconnected ends of both turnbuckle bodies, and
secure with 3/4” locknuts threaded fully onto the eyebolt shaft, but not further
than 1/4”.
5. Thread the second truss cable (3) through the cable return bracket (7) on the
underside of the upper tube, and pull the cable through until there is an equal
length of cable on each side of the tube.
6. Pull the ends of both cables over the truss cable supports (8), and secure the
truss cables to each truss cable support with a 1/2” cable clamp (9), ensuring
that the cable clamps are loose enough that the cables remains free to move.
7. Thread the unconnected ends of the second cable through the unconnected
eyebolts (1) on the turnbuckle bodies, pull tight, and then secure with two
1/2” cable clamps (2). Tighten securely.
8. Tighten the cables by adjusting the eyebolt locknuts. These cables must be
very tight.
9. If the tube has a curve to one side, tighten the turnbuckle on the opposite
side, while loosening the other turnbuckle slightly if required.
10. Tighten all cable clamps securely.
