Front Gate - Fencing Attachment Pole

The picture below is of the attachment point for the field fence once it reaches a gate.  The approach is nice as it keeps you from wrapping the ends of the field fence around the pole where the gate opens and closes.  I plan to mimic this as I expand the original fence to form a fence around the home site area.

  

There are two stand off pieces which are roughly 2" x 2" x 1/4"

The rod is around 52" tall and is 3/4" in diameter.  I'll have to pick these up at a steel supply company.  My planning shows that I will need to add nine of these two the fence when my plan is complete.  I'll need quite a bit of the pipe as well.
