fischer has added the new DuoXpand frame fixing to its successful fischer DuoLine – the product family now consists of five intelligent plugs with an innovative combination of materials.
With its latest addition, the DuoLine now covers multiple applications and construction materials. The ingenious combination of materials and design guarantees a particularly firm bite in all anchor substrates.
The special lamella geometry gently expands in the respective construction material while 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 with 50 mm in concrete, solid and hollow construction materials and 70 mm in all building material classes, from concrete to aerated concrete. Two additional anchoring depths of 140mm and 160mm expand the range of applications to hollow construction materials with large cavities.
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 hexagon 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 permanent, secure fixing. The respective version with a countersunk head or a hexagon screw can be used to carry out facade, ceiling and roof substructures made of wood and metal.
