We attached two of these together and placed it in a rectangular shape around the doggy doors so our dogs could go in and out safely whether we are home or not. As it is a permanent structure we placed a fence stake at the corner of each section and ziptied it to the fence and also used the ground anchors that came with the fence. We also have 2 of them sit up in our great room to contain our dogs when we have visitors as they can get a little wild when excited. I just bought two more so I can fence off the front porch so the dogs can come out in front while I'm working on the lawn.
