The fischer DuoPower is an intelligent two-component anchor with three functional principles. This smart universal anchor is suitable for fixings in all building materials, allowing for a wide range of applications with just one anchor. The fischer DuoPower automatically adapts to the building material and achieves the highest load values through its three functional principles: folding, expanding, and knotting. The excellent feedback from the anchor when screwing in the screw provides an additional level of safety. The fischer DuoPower 6 x 50, 8 x 65, and 10 x 80 are particularly suitable for fixings in hollow building materials, aerated concrete, and for bridging plaster due to their greater anchoring depth.
