I found that 3" thin wall irrigation pipe will slip over 3" PVC which in
turn will slip over 3" chain link fence end posts (mine measures 1/4" wall,
2 3/4" od). I plugged the inside of one end of an 18" length of 3" PVC and
put a coupling sleeve on the other end. I use the end posts for the
support, slip the PVC over the end post and then slide the irrigation pipe
over the PVC.
Take a ruler to your local Home Depot and do some measuring. You may be
able to install a piece of end post in the concrete and mount everything on
I didn't use concrete - I drove a stake through a 12" square piece of sheet
metal and into the ground, leaving a couple of inches of the stake
protruding up. I use this pin as a swivel so I can raise and lower my guyed
80m 4sq elements. No problem with arcing through the PVC and I do run full
