A board-on-board fence, often referred to as a shadowbox fence, is a type of fence that offers visual appeal and seclusion. To create a shadow effect, pickets are positioned on opposite sides of the fence rail.
The concept calls for putting pickets on either side of the rails that cross the fence posts horizontally. Because of the staggered arrangement of the pickets, which alternates between either side of the rail, air and light may pass through while offering some degree of seclusion.
