My kinetic sculptures come with a bracket that fit standard size pipe (I dont ship poles unless you want to pay $25.00 shipping for a $10 pole. My smaller pieces have a bracket that fits a one inch .I.D.water pipe available at any hardware store. Galvanized is best.
To install on your pole dig a hole 16 in deep by 8 inches wide and set in pole.
then prop the pole in a level position and add one bag of Quick-crete and water .
When you have completed that check the pole for level again.
The pole must be level for the piece to work properly.
