- For anchorage in concrete and masonry
- Extremely flexible application thanks to up to three effective anchorage depths
- Extra-long versions for large fixture thicknesses, for example, for fastening through insulation materials
- With metric connection thread for direct fastening of e.g. pipe clamps
- High loads
- Very low spacing and edge distances thanks to very low expansion effect
- Very fast and easy installation, particularly overhead, and immediate load-bearing capacity
- Fastening can be adjusted up to two times after installation (please refer to the installation instructions)
