- Extremely flexible to use due to three anchoring depths
- Extra-long versions for large fixture thicknesses, for example, for fastening through insulation materials
- With stud thread for direct mounting of e.g. pipe clamps
- High loads
- Smallest axial and edge clearance due to very low expansion effect
- Very fast and easy assembly, particularly overhead, and immediately load-bearing
- Attachment can be adjusted up to two times after assembly (please refer to the assembly guide)
When installing with a tangential impact screwdriver, the recommended maximum rated torque must be observed. The maximum installation torque specified must be observed when mounting the attachment parts.
