- 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

When installing with a tangential impact driver, the recommended maximum rated torque must be observed.
When used in masonry, the stone-specific installation data according to ETA-23/0196 must be observed.

| 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. | ||||||||||
