I meant do they have a specific name brand/model. The only thing I found similar is a bunk feeder, but they are only 8" deep. Not quite deep enough for grow beds.
I found them at a local farm & ranch supply store called "Atwoods". However, that is a very regional store. Here in Oklahoma there are quite a few farm and ranch supply stores (probably at least one in most every town) since this is cattle country. I'd try any kind of agriculture supply, they may be able to order them if they don't carry them in stock.
