Open stalls...cool concept.
Horse shoe gate latches
PVC, saddle blanket/saddle pad rack, DIY
horse shelter - simple storage room on the side and gate to contain horse if required.
Horse Barn with Tack Room
Another stalling idea.
For the Horses
Gates to be used as outside paddocks or temporary stalls- install with horse safe latches. when opened, they swing back to create an open aisle.
