Complete your tapered window box cage with our galvanized tapered window box liner. This tapered window box has been constructed out of galvanized metal. We choose metal that has been galvanized as it has been dipped in zinc to help protect the metal against rust. We take it one step further and powder-coat the window box once it has been constructed to protect against the constant moisture soil and plants have. This window box liner measures 24" in length x 8" in width x 7.5" in height. This liner was designed to install inside one of our metal tapered window box cages, but it is pretty enough to stand alone as a window box. Optional brackets are available to mount this under a window or on a wall to enhance your outdoors with colorful flowers and plants.
