Ideal for fastening mounting rails, panel materials or fire-protection panels, zinc-plated steel
  • For anchorage in concrete and masonry

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

  • Fastening can be adjusted up to twice after installation, for example in order to align anchor plates or rails (please refer to the installation instructions)

  • High admissible loads

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

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

Notes:
For further details on compressive strength, edge distances and spacing and installation positions, please refer to ETA-23/0196
To determine the admissible load, the partial safety factor from ETA γM=2.5 was taken into account on the resistance side and a partial safety factor γF=1.4 on the impact side.
The specified values apply to an individual anchor in masonry with fvko: 0.15 [N/mm²] and σd: 0.2 [N/mm²].
For combinations of tensile and shear loads, bending torques or reduced edge distances and spacing, please see ETA-23/0196.
Documentation for brick removal must also be provided.

1) The partial safety factors of the resistances yM regulated in the evaluation/approval and a partial safety factor of the effects of γF = 1.4 have been taken into account. For a combination of tensile and shear loads, for the influence of the edge distance and anchor groups please see the appropriate guidelines e.g. DIN EN 1992-4.
2) The concrete has normal reinforcement. Higher values are possible for higher concrete strengths.
3) The admissible loads were determined without axial influence and the influence of the edge distance.
4) Number of attachment points ≥ 3 and at least one anchor per attachment point produces a load per attachment point of Fperm ≤ 1.4 kN or number of attachment points ≥ 4 and at least one anchor per attachment point produces a load per attachment point of Fperm ≤ 2.1 kN. The admissible loads can be increased if the design shows that the requirements governing the strength and rigidity of the component to be attached remain satisfied even after the failure of an anchor in terms of the limit state of serviceability and load-bearing capacity.
5) The assembly data must be observed.
