Variants

  • For anchorage in concrete and masonry

  • Extremely flexible application thanks to up to three effective anchorage depths

  • Extra-long versions for large fixture thicknesses, for example, for fastening through insulation materials

  • With metric connection thread for direct fastening of e.g. pipe clamps

  • High loads

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

  • Very fast and easy installation, particularly overhead, and immediate load-bearing capacity

  • Fastening can be adjusted up to two times after installation (please refer to the installation instructions)
