Anchor with a smart bite

The fischer frame fixing DuoXpand is approved for multiple fixings of non-structural systems in concrete, masonry and aerated concrete with the fischer safety screw. It guarantees a safe hold in all building materials classes. Thanks to its special lamella geometry and material combination in particular, the plug expands gently and reliably in the respective building material. The pre-mounted safety screw is matched perfectly to the plug and saves time during installation.

The advantages at a glance

Perfect combination
The combination of design and material adapts to all building materials and enables universal use.
The main body
The grey main body made of high-quality nylon provides the strength, while the red material component ensures flexibility and optimal spreading.
The special lamella geometry
The special lamella geometry expands gently in the respective building material. This avoids fractures in porous building materials and enables anchoring close to the edge.
European Technical Assessment (ETA)
The European Technical Assessment (ETA) for multiple use for non-structural applications ensures secure hold in all building material classes.
Pre-mounted safety screw
The pre-mounted safety screw is perfectly matched to the plug and ensures time savings during installation.

The DuoXpand at a glance




  1. The clever combination of design and material bites perfectly into all building materials for universal use.
  2. The special lamella geometry expands gently in the building material and avoids fractures in porous building materials. Thus, anchoring close to the edge is possible without any problems.
  3. The grey main body made of high quality nylon provides strong hold, while the flexible, red material component ensures optimal spreading.
  4. Countersunk head screw and conically shaped plug rim are especially suited for wooden constructions.

  1. The ribs on the sides prevent rotation in the drill hole for a functionally safe assembly.
  2. The expansion element with two anchorage depths enables flexible use in all building material classes according to ETA.
  3. Two additional anchorage depths of 140 and 160 mm allow safe anchoring in perforated materials with large cavities.
  4. The wide plug rim avoids contact corrosion and seals the drill hole for a permanently secure fixing.
  5. The FUS version with hexagon head screw and moulded washer is perfect for metal constructions.
