ok, I picked up some more for the dog run. The normal cable tighteners looked to small and weak, like for a gate or something. So for a couple dollars more, I pick up a top link for a 3pt on a tractor! This will give me my adjustment for as the cable stretches over time. Also picked up grade 8 bolts to bolt everything together. I figure this is the most economical and strengthy way to do it. Plus, its simple.
