The walls should be fully enclosed to a height of at least 1.07 m to prevent horses from getting their legs caught in any railings. Railings above 1.07 m can be 230 mm apart. Alternatively, the walls may be solid for the full height. Walls may be of wood, and rubber conveyor belting is often used to line them.
