Product Description

The fischer DuoXpand T Frame Fixing’s clever combination of materials and design means it can adapt to all building materials, for universal use. Made from zinc plated steel, the countersunk head safety screw is particularly ideal for fixing timber constructions to masonry. For example, concrete, brick and breeze block, including hollow blocks and perforated material.

The DuoXpand is also suitable to use on dot and dab walls, with anchor lengths from 80mm up to 230mm. For example, the 8x120mm will suit a dot and dab wall with a max. void of 25mm and max. plate thickness of 13mm. Its design means that it sits perfectly in plasterboard with no damage.

If you are fixing metal to masonry, we recommend the FUS version of the DuoXpand. This has a hexagon head screw and moulded washer.

The DuoXpand is part of fischer’s DuoLine range of wall plugs. For more information on the complete range, please see our buying guide Why Choose the fischer DuoLine Wall Plug Range?.

fischer DuoXpand T Advantages

  • The plug is made from nylon for strength, with a flexible red “lamella” that gently expands to suit the respective building material. This avoids fractures in porous building materials and enables anchoring close to the edge.
  • Ribs on the nylon plug prevent rotation in the drill hole.
  • The zinc plated steel countersunk head screw is pre-mounted, saving installation time.

fischer DuoXpand T Functioning

  • The DuoXpand is suitable for push through installation.
  • In solid building materials, the product design guarantees equal load distribution into the substrate.
  • In perforated brickwork, the lamellas expand at the stone web and form an undercut in the cavity. The anchor geometry ensures that the force transfers evenly to the material. As a result, there is no destruction of the porous stone webs.
  • Two anchorage depths of 50mm in concrete, solid and hollow bricks. 70mm in all building materials classes, from concrete to aerated concrete.
  • Additional 140mm and 160mm anchorage depths in plug lengths 160mm and over. These depths enable secure anchoring in perforated building materials with large cavities.
