Quick and simple fitting

Push-through installation

Quick and cost-effective assembly

  • It is preferable to install the W-BS Compact manually.

  • If a cordless drill is used for assembly, at least 5 preliminary tests should be performed on location to ensure the correct screwdriver setting and to prevent overtightening of the W-BS Compact. It is recommended that you start with the screwdriver's lowest torque setting and increase it if necessary.

  • A tangential impact screwdriver should not be used for assembly.
  • ETA-15/0091 for multiple attachment of non-load-bearing systems in concrete

  • Fire resistance: R30, R60, R90, R120; Technical Report TR020
