- For anchorage in concrete and masonry
- Extremely flexible application thanks to up to three effective anchorage depths (size 6-14)
- Fastening can be adjusted up to two times after installation (size 6-14), 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
