The fischer DuoXpand extension anchor with two anchorage depths and its fischer countersunk or hexagonal screw is approved for multiple fixing of non-structural applications in all building materials (concrete, solid and hollow masonry and aerated concrete) .
Due to its special lamellar geometry and the material combination, the dowel expands optimally and gently in the building material. The range includes diameters 8 and 10 and dowel lengths up to 230 mm. The DuoXpand with countersunk head screw is particularly suitable for fastening wooden elements and the version with hexagon head screw and integrated washer is ideal for metal structures in concrete and masonry.
Ingenious combination
Bi-material anchor that adapts to all building materials and allows universal use.
Nylon body
The gray main body made of high quality nylon ensures the strength of the binding, while the spacing of the slats provides additional security.
Patented geometry
The patented geometry ensures smooth expansion in the building material thus avoiding damage to the walls of hollow materials and allowing anchoring close to the edge.
Pre-assembled safety screw
The pre-assembled safety screw is perfectly adapted to the dowel and saves time during installation.
European Technical Assessment
The European Technical Assessment (ETA) for multiple use for non-structural applications guarantees a secure hold in all materials of construction.
