Fischer Duopower RB K

The fischer DUOPOWER offers very good holding values thanks to 2 components: The gray component made of high-quality nylon automatically activates the optimum functional principle (spreading, folding, knotting) for the best hold, depending on the building material. The expansion wings of the red component support secure spreading and offer additional security to the gray component. Easy screwing in of the screw and correct tightening at the end. No over-tightening of the screw. The edge formed on the plug head prevents the plug from slipping into the drill hole.
