There are probably more of them out there, but this is the only one I'm aware of
https://modthesims.info/downloads/a...sort=0&u=112249 (bottom row, the horse fences). They are in deco, can't remember if sculptures or misc., and cheap...like 1or 5 simoleans. I sometimes play an Old West hood and they came with this lot
http://www.all4sims.de/board/fileba...leid=3413&lim=0 I don't believe they actually stop movement though, so if that is a concern you might need to add an invisible wall/fence which I'm too lazy to look up, but I think is Numenor's domain. Here on MTS also for that. Good luck and hopefully you get more responses.
