DuoPower – Expansion Plug 2K

The duo of power and intelligence.

The fischer 2 K-Nylon Plug DUOPOWER is suitable for prepositioned and push-through installation. The duo of two different materials and its multi-functional abilities (expanding, folding, and knotting) extend the range of applications to additional materials with top loads. The plug has received great feedback, with users commenting on the feel-good factor. You can feel exactly when the plug is installed perfectly.






  1. Short anchor length allows fast fixing without long drilling using shorter screws.
  2. The connection of soft and hard components enables an optimally matched screw-in and tightening torque.
  3. Red expansion wings support the safe spreading and offer additional safety to the nylon base.
  4. The basic body made of high-quality nylon automatically activates the optimum functional principle for permanent and secure fastening, depending on the construction material.
  5. Narrow anchor edge prevents slipping into the borehole.

fischer DUOPOWER product highlights



  1. Functional zone I: the dowel point spreads in two directions for higher pull-out forces in problematic building materials.
  2. Functional zone II: the spreading element spreads at a 9 degree angle to zones I and III and ensures optimum screw guidance.
  3. Functional zone III: the rear area of the anchor folds or spreads, depending on the building material.

fischer DUOPOWER product highlights










  • The grey component made from high quality nylon automatically activates for the optimum product function (expansion, folding, knotting) for the best hold.
  • The red expansion wings support the safe expansion and offer additional safety for the grey component.
  • The smooth-running opening allows the simple positioning of the screw and the secure guiding and fixing in the screw channel.
  • The required screw length is given by the plug length + fixture thickness + the screw diameter.
  • Suitable for wood and chipboard screws, as well as stud screws.
  • In the case of fixing boards, the thread-less part of the screw must not be longer than the fixture.



  • Two material components for even more applications and top load values in hollow building material.
  • Intelligent self-activating functioning (spreading, folding, knotting) depending on the substrate, for a wide range of applications.
  • Best possible feedback (feel-good factor) of the plug. You can feel exactly when the plug is installed perfectly.
  • The pronounced rotation protection prevents rotation in the drill hole during installation.
  • The smooth running opening enables an easy activation of the screw and a safe installation into the screw channel.
  • The longer versions have additional “bite” in problematic building materials.
