Description FIXtrainer Dowels DUOPOWER Electrician. The duo of two material components ensures secure functions and allows for high loads. The dowel activates the optimal functional principle (expansion, folding) depending on the building material for the best hold. Suitable for wood, chipboard, and stock screws. Screw length = dowel length + component thickness + screw diameter. In panel materials, the unthreaded part of the screw must not be longer than the component thickness. Two material components for the best load values in solid, hollow, and panel materials, with intelligent, self-activating functions (expansion, folding) depending on the substrate. For a wide range of applications. Optimal feedback from the dowel. You can feel that the dowel is perfectly seated. The narrow dowel rim prevents the dowel from slipping too deep and is suitable for pre- or through-mounting. No annoying rotation of the dowel during installation, thanks to the pronounced anti-rotation features. The easy-running opening allows for simple screw placement and secure guidance and fixation in the screw channel. Technical data: Contents: 300 pieces.
