Spiral Diameter

The spiral diameter (500 mm, 600 mm, 900 mm) is selected individually for every secured facility or sector.  First of all, maximum effectiveness has to be achieved; then goes the possibility and convenience of installation.  The bigger the diameter the greater the effectiveness, though the cost of the running meter increases as well.  Please note that, as a rule, by 'coil diameter' the transportation dimensions are meant.  The spiral diameter decreases after stretching and installing.  For example, a 500 mm spiral will shrink to 450 mm after installation.

Clip

This heavy duty clip  is manufactured to have a thickness of 1.6mm and an overall width of 10mm, and is available in either galvanized or stainless steel.  This clip, once fastened to the razor wire, requires a force of approximately 1000 newtons before showing signs of opening, making it very difficult to remove, even with specialized tools.
