The fence section is made of plastic material. The hollow chambers are separated by pinch off regions. The fence section provides a visual block and has a similar appearance on either side of the fence section. The fence section has a post edge and a panel joining edge. The panel joining edge is adapted to engage and overlap with a second fence panel section.
