I was wondering about these when at the
PDC, now after reading this thread I am thinking these might be a great idea for my property when I start fencing it.
I have lots of rock and very rocky soils that are a pain to try and put posts into. So some rock jacks would make life a lot easier to secure posts.
I was wondering how I was going to do some of the fencing, and didn't like how I saw a lot of the 4 strand barbed wire fences around here did things. But these rock jacks seem like the right thing to do the job well.
