the fischer DUOPOWER offers very good holding values thanks to its 2 components: The gray component made of high-quality nylon automatically activates the optimal operating principle (spreading, flaps, knots) depending on the building material for best support. The expansion wings of the red component support the safe spreading and provide additional safety to the gray component. Simply screw in the screw and "pull" correctly at the end. Do not overtighten the screw. The edge shaped on the dowels head prevents the dowels from sliding into the drill hole. The supplied screws are optimally matched to the fischer expansion nozzle DUOPOWER.
