Replacement face-shield window
The Fibre Metal 4178CL is a clear propionate visor designed to slot into compatible Fibre-Metal headgear. Injection-moulded construction gives an exact fit and added thickness for impact protection. Angled shaping allows unrestricted head and body movement while the wide-vision lens preserves peripheral sight. Sold as a single replacement unit.
Users needing a spare or upgrade window
Workers who require a fresh clear visor for existing Fibre-Metal frames will find the correct match here. The part is specific to Fibre-Metal mounting points and will not fit other brands or generic headgear systems. Buyers who need tinted, shaded or coated lenses must select a different model. Anyone without compatible Fibre-Metal headgear should look at complete face-shield assemblies instead.
Propionate material and 4178 part number
The visor is made from injection-moulded propionate rather than polycarbonate or acetate, which determines its chemical resistance and optical properties. The 4178 designation confirms compatibility with the corresponding Fibre-Metal headgear range. Verify the part number on your current equipment before ordering to ensure the window locks securely into the frame.

Questions about this item
How is the 4178CL face shield window installed on the headgear, and what step is often missed?
The window slots into the headgear frame using the angled edges for alignment; the step often missed is pressing both sides evenly until the tabs click fully into the retention slots.
What maintenance or replacement will the 4178CL propionate window need over time?
Inspect the clear propionate surface regularly for scratches, crazing or chemical clouding; replace the window immediately when vision is impaired or the material shows signs of degradation.
What limit appears first on the 4178CL window during sustained use in high-heat or chemical environments?
Propionate softens and can craze under prolonged heat or solvent exposure, so optical clarity loss is the first limit reached under those conditions.
