What Makes DuoLine So Special?

At the heart of DuoLine is a clever fusion of materials and design. Each anchor automatically decides whether to expand, fold or “knot” depending on the substrate, be it solid concrete, hollow block, plasterboard or panel material. This means one anchor type can suit many scenarios, boosting holding power and safety across a wide variety of building materials.

The aesthetic, recognisable red-and-grey design not only enhances visual appeal but also signifies high performance. It offers more component technology, more function and more benefits, translating into both intuitive installation and outstanding load-bearing results.

DuoLine Product Range: More Options for Every Job

Within the DuoLine umbrella, fischer offers multiple variants tailored to specific needs:

DuoPower: The universal anchor featuring three functional zones; it reacts automatically to the building material and offers excellent holding values in everything from concrete to perforated bricks.
DuoBlade: A self-drilling anchor ideal for plasterboard, gypsum fibreboard and lightweight panels. It installs quickly and cleanly thanks to a hard metal tip and anti-rotation features.
DuoTec: Designed for high-load board applications, this toggle anchor snaps open behind panels for a strong hold without specialised tools.
DuoXpand: A frame‑fixing solution for heavy-duty materials such as aircrete and hollow block. It uses lamella geometry and dual anchorage depths to ensure secure edge fixation and fracture protection.
DuoSeal: Specially designed for wet areas like tiled bathrooms, it seals drill holes without silicone and comes with stainless steel screws to meet DIN 18534 and ETAG 022 standards.
