Measure and Cut the Cables
Note: This particular system consists of a cable, a couple of turnbuckles and a fastening device (Image 1). The cable itself is 3/16" — the most popular residential choice. All the ends of the cable terminated inside the turnbuckle, which gives a nice streamline look. Know that there are several options available for this type of project.
Measure for the cable length by extending the turnbuckle all the way open (Image 2) until the "set" screw stops you. The correct length is from the end of the turnbuckle to the beginning of the flare on the terminal end. The turnbuckle goes into the crimp 2", so be sure to add that 2" to the measurement for the proper length of cables.
Cut the cables to length with a sharp cable cutter.
It's vital that the cable cutter blade be sharp. It's difficult to fish the cables through the holes if the ends are frayed.
