Our insurance company made us fix our railing because the spindles were to far apart. As soon as I found this kit I realized exactly what I needed to do.
I cut out all of the iron spindles with an angle grinder, brought in 4x4 post with brackets into the concrete. Drilled the holes for the cables using an extremely long drill bit (1/4 inch x8"). I purchased the cable from Home Depot (50ft for $18) and I ordered 4 sets of metal screw on clamps from Home Depot (which helped me avoid buying the swage tool).
The most awesome part about this kit is the longer 2 sided bolt parts. They enable you to have slack in our line so it's simple to set up and once your completed clamping the pieces on, you just spin it to secure it.
Will absolutely recommend!!
