FBN II Throughbolts

Fixing RJ Facades Helping Hand brackets to concrete

The bolt anchor FBN II is a steel anchor for cost-effective fixations in non-cracked concrete. Thanks to its long thread and the two anchorage depths, the bolt anchor FBN II is particularly flexible.

In addition to pre-positioned and push-through installation, the bolt anchor is suitable for stand-off installation. In the stainless steel design, the bolt anchor is suitable for façade sub-structures, cantilevers, and ladders outside.

  • Technical Characteristics


    FBN II offers maximum load-bearing capacity in non-cracked concrete

    Reduced anchorage depth reduces drill time - this saves time and reduces reinforcement hits during drilling

    Long thread allows stand-off installations and variable usable lengths

    Diameter 8 to 20 mm also for reduced anchorage depths, e.g. for small loads or if reinforcement is hit

    Embossed letter on the head for subsequent control of the installation as it indicates the setting depth
