Expansion anchor Fischer DUOPOWER 8 x 65 S LD

The Fischer DUOPOWER 8 x 65 S LD is a multi-purpose expansion anchor designed for reliable fastening in concrete and other common building materials. Combining two different components, the anchor adapts its function—expansion, folding or knotting—depending on the substrate to achieve secure hold. The set includes screws matched to the plug for correct installation and consistent performance.

Advantages

The two-component design automatically selects the optimal fixing mechanism for the substrate: grey nylon elements activate expansion, folding or knotting while red expansion wings provide additional support and secure widening. A preshaped edge on the plug head prevents the anchor from slipping into the drill hole. Screws supplied are dimensioned to suit the DUOPOWER plug, enabling easy screwing and correct tightening without over-tightening.

Suitable for

• Concrete
• Solid masonry
• Hollow and perforated bricks (depending on load and application)
• General interior and exterior fixtures where an 8 x 65 mm anchor is required

How to use

Drill a hole with an 8 mm drill bit to a depth of at least 85 mm, then clean the hole from dust. Insert the DUOPOWER plug flush with the substrate so the preshaped edge rests against the surface. Place the fixture and drive the supplied screw into the plug until the plug expands and grips the base material. Tighten until the fixture is secure; the design prevents over-tightening.

Usage recommendations

Check the base material before installation and select the correct drill bit and screw length for the application. Observe manufacturer guidance for load values and spacing when planning fixings.
