Description FIXtrainer Dowels DUOPOWER Electrician. The duo of two material components for secure functions 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, particle board, and stock screws. Screw length = dowel length + thickness of the attachment + screw diameter. In panel materials, the unthreaded part of the screw must not be longer than the thickness of the attachment. Two material components for the best load values in solid, hollow, and panel materials, and 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 easy placement of the screw and secure guidance and fixation in the screw channel. Technical data: Contents: 300 pieces.
