Abstract: A fence is characterized by interchangeably mountable fence sections each having a front and a rear surface, and parallel pairs of vertical and horizontal edges. A mounting member having a mast-receiving opening therein is disposed adjacent each vertical edge of the wall portion of each of the fence sections. Each mounting member has a mating surface thereon disposed in the same plane as the mating surface provided on the other mounting member. When the first mating surface on the wall portion of a first fence section is matingly engaged with a mating surface provided on the other of the mounting members on a next-adjacent fence section, the mast-receiving openings therein are disposed in vertical registration. The fence section, including the wall portions and the mounting members, are integrally fabricated of a plastic material.
