## Features

- UNIVERSAL: DuoPower is the first dowel that independently decides whether to expand, bend or knot, automatically adapting to the material and thus allows a wide range of applications in solid, perforated and panel construction materials.
- FAST: The compact size of the dowel allows you to optimize drilling times for easier and faster fixing.
- Easy: DuoPower gives the installer a greater feeling: you immediately understand when the dowel is perfectly installed. Easy screwing is also safe thanks to the side wings and thin collar that prevent the dowel from rotating and slipping in the hole during installation.
- Suitable for: fixing shower curtain rods, curtain rails, mailboxes, lamps/chandeliers, motion and smoke detectors, signs and house numbers, shelves and shelves, bathroom accessories, paintings, cabinets, kitchen cabinets, shelves, extractor hoods, etc.
- Specifications: Hole diameter in wall: 8 mm; Minimum depth of hole to be drilled in the wall: 55 mm; Max thickness can be fixed with screws provided: 5 mm
