The nylon fixing for the stress-free stand-off installation of window and door frames.
The fischer window frame fixing F-S is a special fixing for stress-free stand-off installation of window and door frames. This consists of a fixing made of high-quality nylon and a countersunk head screw made of zinc-plated steel with cross-slot recess. The F-S is set in the time-saving pre-positioned installation. When the screw is tightened, the plastic cone, reinforced with glass fibre, is pulled into the fixing sleeve and expands itself against the hole wall. This means that the window frame is fixed in a stress-free manner in solid and hollow building materials.
