Reliable fastening
- Concrete specialist due to general type approval for individual fixing point in concrete
- Reliable follow-up expansion capability due to ingenious anchor geometry
- The teeth expand in four directions and claw into the base material
- Anchorage via friction locking between anchor sleeve and base material
- High loads due to expansion in four directions
- Improved load transmission through even, continuous load transfer across the entire expansion area
- Virtually no spinning of the anchor sleeve due to low installation torque and expansion
- Anchor sleeve made of high-quality polyamide
- Very strong anti-rotation lock
- Does not require an additional U-washer and prevents contact corrosion
Easy to install
- Time savings due to immediate load-bearing capacity
- Minimal installation work because the anchor sleeve and special screw are pre-assembled
- Hammer-in stop prevents premature expansion of the anchor during installation
Multiple embedment depths
- Masonry: Two embedment depths (50 and 70 mm)
- Concrete: Three embedment depths (40, 50 and 70 mm)
European Technical Approval ETA-11/0309
When anchoring in solid brick and solid sand-lime block, we recommend performing pull-out tests due to differences in brick manufacturing.

Datasheets(X)
- Suitable for fastening façades, suspended ceilings, roof substructures made of wood or steel, wooden beams, wooden laths, angle brackets, wall-mounted cabinets, shelves etc.
