Add the "Falling Water" planter cage along window frames, fences and railings and enjoy the gently curved design. This graceful window box and liner combination is made from steel with a black powder coated finish - a baked on paint that is resistant to weather-related corrosion. The steel cage measures 42"L x 9"W x 9"H and we feature a choice of several liner options to accompany. Choose white cellular PVC at no added charge, or select one of our powder-coated galvanized metal liners for a nominal added cost, or choose the creme de la creme: a real copper liner that will patina over time . Homeowners love the fluid lines of this black planter cage, especially when highlighted by fresh greenery and vibrant blooms. Mounting is on the back of the cage via steel strap. Hardware is available for separate purchase.
