Ideal for fastening pipe clamps or spacer sleeves, zinc-plated steel

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)

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)

Notes: For further details on compressive strength, spacing, edge distances and installation positions, please refer to ETA-23/0196 To determine the admissible load, the partial safety factor from ETA γ_M=2.5 was taken into account on the resistance side and a partial safety factor γ_F=1.4 on the impact side. The specified values apply to an individual anchor in masonry with f_vko: 0.15 [N/mm²] and σ_d: 0.2 [N/mm²]. For combinations of tensile and shear loads, bending torques or reduced spacing and edge distances, please see ETA-23/0196. Documentation for block removal must also be provided.
