The fischer DuoPower is an intelligent 2-component plug with three functional principles. The intelligent universal plug is suitable for fixings in all building materials. This enables a wide range of applications with just one plug. The fischer DuoPower adapts automatically to the building material and introduces the highest load values through the three functional principles of folding, expanding and knotting. The very good feedback from the plug when the screw is screwed in provides additional security. The fischer DuoPower 6 x 50, 8 x 65 and 10 x 80 are particularly suitable for fixings in perforated building materials, aerated concrete and for bridging plaster due to the greater anchoring depth.
