A perimeter security system may need to be installed at facilities requiring a very high level of protection. For such cases, the Cobra double concertina barrier is used. Today, the Cobra razor-cut barrier offers a more effective protection technology than similar Egoza concertina systems. The Cobra barrier is suitable for strategic facilities, nuclear power plants, large industrial sites, and other high-security locations.
Cobra is a structure based on Egoza razor wire, as in other types of concertina barriers. The Cobra barrier consists of two Egoza security coils sharing a common longitudinal axis but having different diameters. Both coils form cylindrical structures, with one placed inside the other. The system is mounted on vertical metal brackets. The concertina coils may be fixed on standard brackets or installed on independently rotating mechanisms.
