Our Home/Yard poles are a sectional pole made from 3 sections of 2” diameter x 18GA. wall x 6 ft. long, steel tubing which is galvanized. The sections mate together via a 1.90” diameter extension tube which is pressed and “staked” into one end of the tube and the mating end of the other tube is precision sized to accept the extension tube. On the top section is a pressed in steel dome cap.
