  • Extremely flexible to use due to three anchoring depths

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

  • Very high loads

  • Smallest spacing and edge distance thanks to very low expansion effect

  • Very fast and easy assembly and immediately load-bearing
