Description of the FIXtrainer DuoPower plug with screws. The duo of two material components allows for high loads and secure functions. Depending on the building material, the plug activates the optimal functional principle (expansion, folding) for the best hold. It is suitable for wood, chipboard, and stock screws. Screw length = plug 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 ensure the best load values in solid, hollow, and panel materials, as well as intelligent, self-activating functions (expansion, folding) depending on the substrate. The product offers a wide range of applications and the best possible feedback from the plug. You can feel that the plug is perfectly seated. The narrow plug edge prevents the plug from slipping too deep and is suitable for pre- or through-mounting. No annoying rotation of the plug during installation thanks to the pronounced anti-rotation features. The easy-running opening.
