The intelligent 2-component plug with three functional principles.

Suitable for fixing in all building materials

The fischer DuoPower is a universal plug that adjusts itself automatically to the building material used and can achieve maximum load values thanks to the three functional principles folding, expanding and knotting. This plastic fixing combines two components for an even better performance and thus outshines conventional gypsum plasterboard or cavity fittings.

Your advantages at a glance

Simple start:
The smooth running opening enables an easy activation of the screw and a safe installation into the screw channel.
Simple installation:
No annoying rotation of the plug in the drill hole during the installation, thanks to the pronounced rotation protection.
Perfectly installed :
Best possible feedback (feel-good factor) of the plug. You can feel exactly when the plug is installed perfectly.
Additional versions:
The longer versions have additional "bite" in problematical building materials.
Two material components for even more applications and top load values in solid and hollow building material
Maximum safety
European Technical Assessment (ETA) for certain DuoPower dimensions. Tested safety for safety-relevant applications in concrete and masonry.
