Thanks for the reply Lisa. I went down 24'' square then also went with an 8" tube another 18" in the center. I got 2 free 1/2 " plates and measured and drilled the holes myself. Trying to save money for other things I need.


Don't forget to insert a plastic bag full of dry sand inside the pier. It will minimize any vibrations.
