JC Slotted Hook Bracket
I love these brackets. I've bought 6 of them. Great design and heavy duty. Easy to put together just have two threads from each bolt show through the top of the nut and you know you've got it wide enough to slide easily over the top of a range fence post. FYI: The knobs on the fence post face the firer - just be aware of that when you're putting the fence posts into the ground to put these brackets on.
