It is important to check that the members are correctly installed for the specific construction conditions (e.g. weight of window casement, surface properties, hole pattern in the brick). Fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4 may only be attached with the AMO Combi screw if appropriate individual approval has been obtained before installation starts.

Guidelines for planning and executing the installation of windows and house doors
The fixture must safely transfer all standard forces affecting the window to the structure and the foundation. The total load must therefore be calculated from e.g. the window load, wind load and live load (see DIN 1055). The currently applicable building regulations stipulate that buildings and their components must be planned in such a way that they do not endanger human life and health or pose a risk to public safety. Attachment of the windows must also comply with this criterion.
When securing window walls compliant with the former DIN 18056 standard or elements with a surface area in excess of 9 m2 and fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4, the following must be observed
The DIN 18056 standard applied to window walls with a minimum surface area of 9 m2 and a minimum side length of 2 m on the shortest side. Anchors with construction product approval, European Technical Approval or with individual approval should be used for this application. Similarly, only anchors with construction product approval, European Technical Approval or with individual approval must be used to attach fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4.
