In aerated concrete or perforated brickwork, it will fold to lock between the perforations in the substrate. Even where it is not certain whether there is solid material or a cavity behind the surface DUOPOWER eliminates concern and ensures secure fixing.
A white flange sleeve with snap function allows the toggle to be pre-installed quickly and securely in the drill hole prior to driving the screw, and a scale on the DUOTEC 12 grip strap helps determine the required screw length.
fischer describes the Gypsum Board Screws Manufacturers innovative and technically advanced product as a duo of power and intelligence. Cleverly, where the substrate proves to be solid the DUOTEC will also function as an expansion plug, working in concrete or wood..
In plasterboard or where there is a rear cavity, it knots. Sounds a bit far fetched? Far from it. In solid substrates, like concrete and brick, the plug expands. The DUOTEC nylon toggle, available in 10mm or 12mm versions, uses a soft grey nylon contact surface to distribute the load over the rear panel surface, minimising any weakening of the supporting building material.
