Welding cable (for flexibility) tie wrapped to rings which slide along a stainless cable attached to the adjacent fence. Cable folds and unfolds like curtains on a rod.
Welding cable is good.
For a track I have used double stut (B22A or equal) and a B-Line B376 (or equal) trolley assembly.
The B22A is double stut, use the top channel to bolt to the fence and the bottom to run the trollys in.
Sloap the strut so it moves downhill when your opening the gate, othewise it's pushing the cable.
IF you only open the gate once or twice year there are cheaper trollys in the B-Line catalog.
Ha Ha! suggestion worth considering, but unfortunately I am not allowed to use this option. Any other thoughts?
My first thought is that any copper cable at the gate is pretty much easy target.
Safety requirements will trump any concerns regarding theft. You can probably get tinned copper braid that will not look like copper to your average meth addict.
The ones I did look like the one is this picture. The B22A channel goes between the outside fence fabric and the gate rame. Put it up high. Some on has to reach through the holes in the chain link and cut the cable to steal it. If ypu use welding cable it comes in color. Use orange or yellow and it's easy to tell when it's been stolen.
Everything above is a link. PAste in in and the look at the Gate in Liberty Lake WA
There is a picture above that that shows a roller wheel. The struc with the trollies goes in that plane.
