Window frame fixing F-S

The nylon fixing for stress-free stand-off installation of window and door frames

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.

Product Description

  • The operating principle of the plug prevents the frame from being pulled against the substrate, and ensures a stress-free and long-lasting fixing of the frame.
  • The special plug geometry anchors the metal and plastic profiles against compressive and tensile loads, and allows for a secure hold of the window frame.
  • The cover cap (available separately) can be used to discreetly cover the screw head.

Assembly Instruction

  • The F-S is suitable for push-through installation.
  • By tightening the screw, the glass-fibre-reinforced plastic cone is drawn into the sleeve, whereby it is expanded and wedged inside the drill hole. The window frames are thus fixed in a stress-free manner.
  • The maximum installation torque is 3 Nm for F8S and 6 Nm for F10S.
