KNIGHT DEFENDER® CONCERTINA Razor Wire is recommended for high-security residential and high-security commercial, military and Correctional Institution use. Its needle-sharp long razor barbs are the most effective and economical solution for home and business security. Each loop is clipped to its adjacent loop with Industry Standard CONCERTINA razor wire clips. This system forms an accordion style roll that cannot be stretched beyond it's designed yield and creates a more dense field of needle-sharp long barb razor barbs. CONCERTINA can be easily stacked in same or different diameters to form an impenetrable wall-like barrier. The 24" (60cm) diameter razor wire will increase your perimeter security by 50% in comparison with the 18" (45cm) product. Our CONCERTINA 24 is available in either Stainless Steel (AISI 430) or Galvanized (ASTM A635) reinforced with a cold clenched galvanized steel core. The barb length is the deadly
