Here's what I have:
The play yard is great for small dogs as the configuration is difficult for them to get their widdle paws in to climb. It is 29" tall and 12 feet long. There are no metal parts to rust so can be left outside.
This is a 48" long drop pin. Not as convenient as the folding models if it needs to be moved often, as there are multiple pieces, but if it stays stationary, the lower price vs the folding variety may be worth it. This is 65.00.There are 2 more 48" long drop pins available, both black and have some rust. They are 55.00 each.
