fischer DuoXpand frame fixing

Unprecedented freedom and intelligence in fastening
With its clever combination of material and design, the DuoXpand guarantees a particularly firm bite in every anchoring base. Different anchoring depths and versions with hexagonal and countersunk head screws further increase the flexibility of the fifth member of the intelligent fischer DuoLine family.

The special lamella geometry gently expands the frame fixing in the respective material. The intelligent design guarantees even load distribution in solid building materials. In perforated brick, the lamellae expand along the stone fillet and form an undercut in the cavities. Thanks to its gentle force transmission even in porous construction materials, fractures are avoided and anchorages can be placed close to edges without issue. Made of high-quality nylon, the grey main body offers a strong hold while the red material component ensures flexibility and optimal expansion. The European Technical Assessment (ETA) for multiple use for non-structural systems certifies its secure hold in all building material classes. The expansion element with two anchoring depths increases flexibility.

DuoXpand is available with a countersunk head screw and a conical shaped plug rim, variants which are particularly suitable for timber construction fastenings. The additional DuoXpand FUS versions with hexagonal screws and moulded washers also allow a diverse range of metal construction applications, during which the wide plug rim avoids contact corrosion between the fixture and screw for a permanently secure fixing. The respective version with a countersunk head or a hexagonal screw can be used to carry out facade and ceiling substructures made of wood and metal. The frame fixing’s wide range of applications also includes windows, gates and doors, wardrobes, kitchen cupboards, joists, beams, TV units, wall cladding, metal brackets and much more.
