发明名称 Defensive personnel barrier
摘要 A defensive personnel barrier and method for fabrication thereof includes an elongated metal strip having a longitudinally extending bend therein to form a spine extending therealong with laterally opposed flanges extending obliquely from the spine. Each flange is stamped or die cut to provide a plurality of cuts spaced therealong and extending diagonally from the spine to the outer edge of the flange. The diagonally cut portions are bent upwardly from the plane of the flange to form a plurality of barbs spaced longitudinally in the metal strip. The barbs of the opposed flanges are staggered longitudinally, and the edges of the barbs are sufficiently sharp to discourage manual grasping of the strip. One or more strips may be secured atop a fence or similar barrier to discourage climbing thereon. The barrier strips may also be secured to existing linear barbed wire strands by means of a saddle block and J bracket assembly provided by the invention.
