Metal frame fixing F-M

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.
