Key Features:
- Secure Functions: Adapts to solid (expansion) and hollow/panel (folding/knotting) building materials.
- Intelligent 2-Component Technology: Combines hard and soft components for optimal screw guidance and expansion.
- High Load Capacity: Offers superior load values due to dual-material construction.
- Anti-Rotation Design: Ensures flawless installation and prevents spinning in the drill hole.
- Short Plug Length: Allows for fast installation with shorter screws, reducing drilling depth.

2. Safety Information
Always observe general safety regulations and local building codes when performing fastening work. Wear appropriate personal protective equipment, such as safety glasses and gloves, to prevent injury. Ensure the drill area is clear of electrical wires, water pipes, and other obstructions before drilling. Use the correct drill bit size and type for the specific building material.
3. Installation Guide
The fischer DuoPower plug is designed for easy and optimal performance across various building materials. Follow these general steps for installation:
- Drill the Hole: Use a drill bit with the specified diameter (14mm for this model) and drill to the minimum required depth (60mm for this model). Ensure the drill hole is clean and free of dust.
- Insert the Plug: Push the DuoPower plug into the drilled hole until it is flush with the surface of the building material.
- Insert the Screw: Drive a suitable wood or chipboard screw (1/4" - 5/16" or 6-8mm diameter) into the plug. The plug will expand, fold, or knot depending on the material, ensuring a secure hold.

Functional Zones and Material Adaptation:
The DuoPower plug intelligently adapts its function based on the building material:
- Functional Zone I: Aerated Concrete / Solid Materials
The plug spreads in two directions for higher pull-out forces in problematic building materials like aerated concrete or solid brick. - Functional Zone II: Hollow Building Materials
The spreading element spreads at a 90° angle to zones I and III, ensuring optimum screw guidance and a secure hold in hollow blocks. - Functional Zone III: Drywall / Plasterboard
The rear area of the anchor folds or spreads, depending on the building material, creating a strong knot behind the panel.

5. Care and Maintenance
The fischer DuoPower plug is designed to be a maintenance-free fastening solution. Once correctly installed, it requires no ongoing care. Ensure that the plug is not exposed to extreme temperatures or corrosive chemicals, which could compromise its material integrity.
6. Troubleshooting
If you encounter issues during or after installation, consider the following:
- Plug Not Holding:
- Incorrect Drill Hole Size: Ensure the drill bit diameter matches the plug's diameter (14mm). A hole that is too large will prevent proper expansion.
- Insufficient Drill Hole Depth: The hole must be deep enough to accommodate the full length of the plug and the screw. Refer to specifications for minimum drill depth (60mm).
- Incorrect Screw Size: Use a screw within the recommended diameter range (6-8mm). A screw that is too thin may not activate the plug properly, while one that is too thick may damage it.
- Material Type Mismatch: While DuoPower is versatile, ensure the material is suitable for mechanical anchors. Very soft or crumbling materials may require specialized chemical anchors.
- Plug Spinning in Hole:
- This indicates the anti-rotation features are not engaging. Ensure the drill hole is clean and the plug is fully inserted. The ribbed structure of the plug should grip the sides of the hole.
