- For anchorage in concrete and masonry
- Extremely flexible application thanks to up to three effective anchorage depths
- 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)

Anchorages in concrete, individual fixing point with approval (dia. 6)
In normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete)
Anchors in a redundant non-structural system in concrete, with approval:
- In normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete, (dia. 6))
- In hollow-core prestressed concrete ceilings C30/37-C50/60, (dia. 6)
Anchorages in masonry with approval (dia. 6):
- In solid calcium silicate block and perforated block
- In solid block masonry brick
With metric connection thread, therefore a highly efficient fastening solution in concrete for numerous applications involving technical building equipment such as in sanitary, air-conditioning and electrical installations or for fixtures that need to be removable
Ideal for fastening medium loads in concrete and light to medium loads in masonry:
- E.g. for fastening pipes, ventilation ducts, cable clamps, suspensions with threaded rods, mounting rails, brackets, metal profiles, brackets for façade or ceiling substructures in pre-positioned installation
- Fastenings subject to seismic activity in earthquake-prone areas (only concrete)
- Fastenings subject to exposure to fire
W-BS/S (galvanised steel) may only be used in dry indoor room conditions
For use in concrete < C20/25 and pressure-resistant natural stone (without approval)
