Notice

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.

Instructions

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.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
