Highest loads and efficient installation. For flush-mount installation of e.g. railings or handrails, zinc-plated steel
  • For anchorage in concrete and masonry

  • Extremely flexible application thanks to up to three effective anchorage depths (size 6-10)

  • Fastening can be adjusted up to two times after installation (size 6-10), 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

  • Attractive, flush-mount installation possible

Fire resistance rating when exposed to fire according to the standard temperature time curve in masonry (Mz, KSL, KS) and reinforced concrete, (dia. 5 and dia. 6) - expert report no 2101/173/18 - 2018

Notice

From size 8, we recommend the use of a suitable tangential impact driver for installation. The recommended maximum nominal 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, spacing, edge distances 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 spacing and edge distances, please see ETA-23/0196.
Documentation for block removal must also be provided.
