Method 4 – Using Field Applied Fitting Connections Only (No Cables)

 

If the damaged cable, after cutting, is less than a total of 4’-6” [1.3 m], the connection can be 
made with a left and right threaded field applied fittings and a turnbuckle. 

1.  Remove 4’-6” [1.3 m] of cable from the cable run. 

2.  Place a left-hand threaded fitting on one end of the cut cable and right-hand threaded 

fitting on the other end of the cut cable. 

3.  Follow the procedures in the 

“Field Applied Fittings with Turnbuckle”

 Section. 

 
After completing one (1) of the four (4) methods above, check the tension on the cable with the 
tension meter and adjust the turnbuckles to bring the cable to the correct tension based on the 
cable temperature and the values on CASS

Cable Tension Inspection Program 

 

Trinity Highway recommends the cable tension be checked at least once a year.  The tension 
value is established based on the cable temperature, which can be taken using an IR thermometer 
for the cable temperature.  If an infrared thermometer is not available, obtain the air temperature 
from a reliable source in the immediate area and not influenced by other factors.  See CASS
