A high strength security fence for resisting penetration by vehicles. The fence has high strength line posts that support a plurality of tensioned high strength cables. In the preferred form, these cables are threaded through the posts. The cables are each encased in a conduit-type rail sheath (i.e., superstructure) that span the distance between the posts. Typically, at least one end of each cable is anchored within the concrete anchor of a post adjacent a line post supporting the cable. Cables can be anchored, and tensioned, at corner buttresses if desired. To improve the aesthetic appearance of the fence and to add further strength, the posts and rails can be encased in decorative superstructures, and vertical strengthening bars are joined to the rail superstructure. A clamp is described for joining the high strength fence to upright posts of conventional chain link fences or the like.

An improved high-impact, vehicle-stopping security fence for enclosing an area and surface to be protected, said fence capable of withstanding impact by, and imparting disabling damage to, a vehicle potentially intruding into said area, at least a portion of said improved fence being arranged in segments, and which comprises: a plurality of high strength line post means positioned along at least a portion of the perimeter of said area and surface to be protected, said line post means including a line post superstructure having a top end extending upwardly from said surface, and a bottom end extending to at least proximate said surface; anchor mean at each of said line post means for securing said bottom ends of said line post superstructure to said surface; a plurality of extra high strength superpost means interposed periodically along the length of said fence, said superpost means including a superpost superstructure having a top end extending upwardly from said surface, and a bottom end extending to at least proximate said surface; superpost anchor means at each of said superpost means for securing said bottom ends of said superpost superstructure to said surface; a plurality of tensioned high strength cables, supported by said line and superpost means, said cables penetrating said superstructure of said line and superpost means and being substantially parallel to each other and to said surface for that portion of their length extending between said supporting line and superposts, said cables each having opposite end portions which together define the limits of a segment of said fence and which extend downwardly from the superstructures of first and second said superposts, being opposite end superposts of a first said segment to, and being securely anchored to and immersed within, said superpost anchor means of second and third said superposts proximate said first and second said superposts, respectively, said second and third said superposts being the end superposts of segments of said fence adjacent to said first and second ends of said first fence segment; a plurality of rail superstructures, each enclosing one of said cables, substantially parallel to said surface for that portion of their length extending between said line and super-post means, said rail superstructures being hollow so as to coaxially receive said one cable, each of said rail superstructures having opposite end portions extending downwardly from a first said superpost superstructure to, and being securely anchored within, said superpost anchor means of a second said superpost proximate said first superpost; securing means at said opposite end portions of said cables to establish and maintain tensioning of said cables, whereby said line and superpost means, said cables, and said rail superstructures are enabled to withstand said impact; and clamp means for attachment of one said rail superstructures to a vertical post of an adjacent fence, said clamp means having a U-shaped body member formed by confronting legs, said body member for embracing said post of said adjacent fence, said legs joined in confronting relationship by fastener means, said legs provided with aligned apertures to receive said rail superstructure.
