The anchoring units each have a first connector on a first end and a second connector on a second end. The first and second connectors are sized to slide into and be interlocked with the channels of the face unit. The distance between the upper surface and the lower surface of the anchoring unit forms its height, which is approximately uniform and is approximately one half of the height of the face unit.
