The fischer board fixing PD is the flexible expansion plug with a high level of installation security for fixings in gypsum plasterboard, gypsum fibreboard and wooden panel material. The high-quality nylon plug is set in pre-positioned installation. When the screw is tightened, the cone is pulled into the sleeve and the plug expands in the building material. As a result, the PD can also be used securely in low cavity depths and in various panel thicknesses. The fischer board fixing PD can be used with the most wide-ranging screws, hooks and eye screws with diameters from 4 to 6 mm. In addition, the fischer board fixing PD S is already available with a corresponding chipboard screw for optimal interaction.
