Our stall door bottoms are wood with the traditional "X" overlay. The tops are metal with a wood topper to enable the air to flow.
We have a name plate (horse barn name), rings (not hooks) for a halter and a leadrope on the stall door. That is all.
I do not want the private owners information available to anyone who walks in the barn. The feeding chart is kept with the feed.
Our barn aisle is the primary area to tack up. Aisle is approximately 10 feet across but a horse standing off center could still poop or splash urine down a stall front. Cat spray, visiting kids cart stuff off . . . .
Less is much better.
