Extremely flexible to use

Three anchoring depths (size 6 - 14) and a large variety of types

  • High load-bearing capacities

  • Virtually no expansion effect, enabling minimal axis and edge distances to be maintained

  • Very quick and easy to install

  • No installation torque required

  • Immediate load-bearing capacity – no waiting

From size 8, we recommend the use of a suitable tangential impact screwdriver for installation.

If several anchors are arranged behind each other in the same load direction, only one anchor is positioned for transverse loads.
