Create extravagant arrangements along window frames and deck railings with grand 72"L window box cages. Luxurious and resilient, the "Garden Gate" flower cage is made from high-grade steel with a powder coated black finish. Every last inch of the 72"L x 9"W x 9"H window box cage is corrosion-resistant for superior outdoor performance and comparably durable liner options include standard white PVC (no additional cost), or planter liners made from real copper and several tones of galvanized metal (pricing will vary). Mounting straps are on the back of the metal cage. Hardware for both railing and wall applications is available for separate purchase.
