This is a corner horse feed for a stall, although I have seen them foot low close to the ground and used for water or feeders for smaller animals. It has never been attached to the wall, but I have stood it up and used it for my lambs a couple times it does have a drain in the bottom and will hold water. If you have any other questions please just ask this one has been in storage for a while. I couldn’t find it when I was selling the other three hope everyone has a wonderful day and thank you for viewing the post
