  • No shading issues therefore optimal roof coverage possible.
  • Quick mounting due to reduced number of components and assembly only from above.
  • Very low dead weight.
  • Tested in the wind tunnel.
  • K2 SpeedRail as a base rail.
  • Static proven solution using the K2 Base Planning Software.
  • In addition system available: K2 building protectionmat, K2 Scale /Scale XL or K2 Porter for simple and quick installation of ballast.
  • Extended range of applications also on profiled sheet metal roofs.
  • Optionally with equipotential bonding / lightning protection.
