MAXIMUM SAFETY ACCORDING TO PATENTED PRINCIPLE CAPRA Protection offers the best protection, secure shielding and highest security - despite its flexibility and mobility. Three main characteristics provide stability: ~ a 810-kg concrete base ~ the massive double bar panels are screwed tight and equipped with brackets on request ~ our patented interlocking system ensures a stable meshing of the concrete base The solid base in combination with the interlocking system makes it almost impossible to move or to tear down the fence. The fence elements are also available with other fillings on request.
