This is a nice heavy duty round pen that is self standing and durable. the railroad ties were added for the gate but they aren't needed for the pen if you don't want them. It is great for training or holding animals. There are a few extra panels that might get it to 60 feet if you want. The pen is held together with bolts that are easy to disassemble. The metal panels are heavy but two guys can move them. You purchase and you disassemble and haul. Located in Lava Hot Springs Idaho It is about 8 feet tall.
