We stock a similar porcupine style structure where I work. They are the
O-NO hang fish habitat. They come in a forest greencolor. They are 1/2 inch pvc with an overall spread of six feet from side to side. Each side piece being three foot pvc 1/2 inch. I have used several of them in the past couple years and am very happy with their fish attracting abilities. Any questions you can go to their site at www.onohang.com or to our web site at www.JaysSportingGoods.com or send me a PM here.
