This wrought iron half-circle fence can wrap around a tree or be used as a trellis. It is sold per section. The picture shows two areas around the tree, so you must order 2 for a surround. It measures 25.5" tall, but after its stakes, it is 19" x 24" wide. A Half section is 12" front to back, but when two sections are together, it measures 24" in diameter.
