Double coil concertina wire. Connect the neighbor spiral by the clips, to form a new spiral and several continuous new spirals forms the double spiral concertina wire. This design can reduce the spacing between spirals and coils to improve the security coefficient than the single spiral concertina razor wire. It is widely used in the military sites, prison, airport and other places where needs high security.
