  • Patent number: 4272060
    Abstract: A privacy fence is disclosed in which ease of assembly is emphasized in a system combining predominantly steel elements. The steel rails are nominally four sided, but they are open on one side to permit the insertion of steel fence panels or louvers. A specially designed clip holds each panel in place and resists pilferage which might be expected from casual vandalism. Except for anchoring the rails to the fence posts, no screws, bolts or nail type fasteners are necessary or used. A variety of visual textures is obtained using these elements in a fence section.
