Metal frame fixing F-M

The fixing for stress-free installation of window and door frames with fire classification

The fischer metal frame fixing F-M is a special plug for the stress-free, lasting stand-off installation of window and door frames and of squared timbers. It consists of a metal sleeve and a zinc-plated steel screw. The F-M is set in a time-saving push-through installation. When the screw is tightened, the 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 solid and hollow building materials. The F-M is tested for fire resistance class R120, and offers safety for fire-protection-relevant applications.

Product Description

Advantages

The F-M metal frame plug achieves fire resistance R 120. This allows for use in areas where fire resistance is relevant.
The operating principle prevents the window 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 caps (available separately) can be used to discreetly cover the screw heads.

Assembly Instruction

Functionality

The F-M is suitable for push-through installation.
By tightening the screw, the cone is drawn into the sleeve and the fixing is expanded which wedges it inside the drill hole. The window frames are thus fixed in a stress-free manner.
The maximum installation torque is 5 Nm.
