The fischer DuoPower is an intelligent 2-component dowel with three functional principles. The intelligent universal dowel is suitable for fixings in all building materials. This means a wide range of applications is possible with just one dowel. The fischer DuoPower adapts independently to the building material and uses the three functional principles of folding, spreading and knotting to enable very high load values. The very good feedback from the dowel when the screw is inserted adds greater safety. The fischer DuoPower 6 x 50, 8 x 65 and 10 x 80 are ideal for fastenings in hollow building materials, aerated concrete and plaster due to their greater anchoring depth. https://elecena.pl/product/29617604/535980-duopower-8x40-bigpack-120-pieces 2025-12-16 https://elecena.pl/product/29617604/535980-duopower-8x40-bigpack-120-pieces 2026-06-28
