Handy storage bucket makes for simple organization and transportation

Fluted design expands on contact with water-based glues for maximum reinforcement

The pronounced rim prevents the plug from slipping into the drill hole, thus allowing for a simple installation

The expansion-free plug neck prevents the creation of expansion forces on the material surface whilst screwing in the screw. This helps to prevent damage to tiles and plaster

The 4-way expansion provides the optimum force distribution in the material, and offers high load-bearing capacities in solid and hollow building materials

Best load values & intelligent function: The DUOPOWER is the first dowel to decide whether it spreads, folds or knots – so it automatically adapts to the respective surface and thus allows a wide range of applications in full, perforated and panel building materials. The supplied screws are optimally matched to the dowel.

Absolutely powerful: thanks to the compact and short shape, significantly less drilling effort and therefore shorter screws are required, when hamming the dowel, the narrow edge prevents slipping into the drill hole, the anti-rotation lock prevents the dowel from turning and thanks to the best possible feedback, you will feel immediately when it is perfect fit.

A dowel for all building materials: as an intelligent 2-component dowel, it offers very good holding values – the grey component automatically activates the optimal operating principle depending on the building material, while the expansion wings of the red component support the secure spreading.
