Multiple anchoring depths and a large variety of types
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 in the approval or the enclosed leaflet)
- 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.
