The simplest solution for suspended installations with threaded rods in sizes M8 and M10. Very efficient fastening solution in concrete for numerous applications involving technical building equipment such as in sanitary, air-conditioning and electrical installations
Ideal for fastening medium loads in concrete and light to medium loads in masonry:
- Fastening of e.g. single pipe and ventilation installations, suspended ceiling substructures, suspended cable and pipe trays
- Fastenings subject to seismic activity in earthquake-prone areas (in 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)
