Window frame fixing F-S

The fischer window frame fixing F-S is a special plug for the stress-free stand-off installation of window and door frames. It consists of a plug made from high-qualify nylon and a countersunk head screw with a cross-slot recess made from zinc-plated steel. The F-S is set in a time-saving push-through installation. When the screw is tightened, the fibre-glass reinforced plastic cone is pulled into the plug sleeve and expands against the wall of the drill hole. This ensures a fixation that is free from tensile force and pressure, thus guaranteeing a secure hold in all building materials.
