The fischer DuoBlade is part of the innovative DuoLine and therefore consists of different components, which enable the best possible performance. The self-drilling tip allows a clean and effective drilling procedure. The fixing is screwed in the pre-positioned installation with the (cordless) screwdriver setting tool flush to the surface of the gypsum plasterboard. The fischer DuoBlade is adapted for wood, metal and chipboard screws from 4 to 5 mm thickness as well as different hooks and eye screws. Consequently, it is universally suitable for fixing e.g. smoke detectors, curtain rods and shutters securely and quickly. The DuoBlade is placed in the plasterboard with a conventional PZ 2 drive. No special setting device is required.
