For sale is a kinetic copper wind sculpture with Three Blades Standing United. The entire wind sculpture including the pole and its fixture is made of pure copper with brass hardware. The stainless steel ball-bearing within the brass hardware allows the triple blades to spin in a slight breeze. The pole is made of heavy gauge copper and secured into the ground by an all copper 4-point anchoring system. With its heavy-duty construction, this kinetic sculpture can withstand strong winds up to 70 mph. The wind catchers and arms are not coated and will age naturally. If you want to preserve its original copper shine, you may spray a layer of clear coat on it. We have had great success with clear coats made by Rust-Oleum (Crystal Clear Enamel) or Permalac (Original Clearcoat Lacquer Satin). The craftsmanship of this kinetic sculpture is impeccable. The sculpture is entirely weatherproof and made to last for decades. We proudly back this beautiful wind sculpture with a lifetime warranty. Size: The entire sculpture (above ground portion) is about 6 ft tall. The spinner head is 28" tall and 24" in diameter.
