Highest loads and efficient installation. Ideal for fastening metal structures, zinc-plated steel
  • For anchorage in concrete and masonry

  • Extremely flexible application thanks to up to three effective anchorage depths (size 6-14)

  • Fastening can be adjusted up to two times after installation (size 6-14), for example in order to align railings or anchor plates (please refer to the installation instructions)

  • Very high loads

  • Very low spacing and edge distances thanks to very low expansion effect

  • Very fast and easy installation and immediate load-bearing capacity
