For sale is ONE kinetic copper wind sculpture with a theme of spinning ficus leaves. The shape of ficus leaves enables the spinner to capture more winds. The leaves are oriented in a way that enables two wheels to spin elegantly in opposite directions at all times. The entire wind sculpture including the pole and its fixture is made of pure copper with brass hardware. The only metal is the stainless steel ball bearings that are completely covered by brass hardware. Two ball bearings make the dual spinners move independently and always in opposite directions. A third bearing makes the kinetic sculpture swivels 360 degrees in the wind. The unit spins in the slightest breeze (notice the motion of real tree leaves in the video). 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 and swiveling head, this kinetic sculpture can withstand strong winds up to 70 mph. The copper leaves 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 and Permalac (Peacock Labs). The craftsmanship on this wind sculpture is impeccable. The wheels are finely balanced and maintenance free. The sculpture is entirely weather proof and made to last for decades. We proudly back this beautiful kinetic wind sculpture with lifetime warranty. Size: Pole is about 6 ft tall. Each wheel is about 2 ft in diameter.
