Functionality: The GB is suitable for push-in installation. The spiral-shaped outer ribs ensure a positive connection between the building material and the anchor. The required screw length is calculated as follows: Dowel length + thickness of the attachment + 1 x screw diameter. To fulfil the approval and achieve the maximum load-bearing capacity, the GB must be used with the fischer safety screw. Applications: Suspended ceilings, cable trays, pipework, railings, façade and roof constructions made of wood and metal, canopy brackets, letterbox systems, trellises. Advantages: The general building authority approval guarantees tested safety for use in safety-relevant applications. The spiral-shaped outer ribs cut positively into the soft building material and ensure optimum pressure distribution and holding values. No special tools are required to hammer them in, saving time and costs during installation. Building materials: Approved for: aerated concrete ≥ PB2, PP2; aerated concrete wall and ceiling panels ≥ P3.3.
