This Arch Decora window box measures 31" in length x 8 ½" wide x 7 ½" in height and is constructed out of steel for extra durability and strength, but gives the look of a wrought iron window box. Our manufacturing process includes powder-coating to protect against rust and corrosion. Our pretty arch design has been very popular and includes mounting straps across the back, giving you flexibility on the location of the installation. These Arch Decora window boxes can be mounted under a window easily or with optional brackets on a wall, fence, or railing. Our galvanized metal liner has also been powder-coated to help resist the effects of constant contact of water. Customization is also available, for specifics give one of our customer service reps a call at 800-896-0978.
