Abstract
A high security fence which includes strengthening cables. The cables extend internally within the aligned rails of the fence, and through cable passageways formed in the posts which support the fence rails. The cables are anchored adjacent each end by a substrate. Anchors are installed on each end of the cable to resist pullout of the cable from the substrate, which may be a concrete-filled bollard post installed in a buried concrete deadman.
