The fischer DUOPOWER offers very good holding values thanks to 2 components: Depending on the building material, the grey component made of high-quality nylon automatically activates the optimal operating principle (expanding, folding, knotting) for the optimum hold. The expansion wings of the red component ensure safe expansion and provide additional support to the grey component. Simply screw in the screw and firmly tug to secure. Do not overtighten the screw. The moulded edge on the plug head prevents the plug from slipping into the borehole.
