I've used this pet gate to keep my dog from running out of the apartment. I have an open patio and I was able to use four of the panels for the front of the patio and unexpectedly discovered it comes apart and the remaining two panels I was able to use to fully enclose the patio. The gate feature is really nice and at first, took a minute to figure out how it opens. Overall it's a great feature. It's free-standing. I'm sure if you wanted to you could bolt it in but for now, it's helpful enough to keep my dog in the enclosed area and enjoy the outdoors.
