The Honeywell Fibre-Metal 4178IRUV5 Impact Resistant Replacement Window, Green Shade 5, is engineered to provide reliable face protection combined with light filtering performance in demanding industrial environments. Measuring 8 inches by 16-1/2 inches, this large-format replacement window integrates with compatible Fibre-Metal headgear systems to form a complete face shield assembly designed to support ANSI-compliant protection. The impact resistant construction helps guard against flying particles and debris, while the Shade 5 green tint assists in reducing infrared and ultraviolet light exposure during tasks such as torch cutting and brazing.A common buyer question is when to select a Shade 5 window instead of a clear or darker welding lens. Shade 5 is typically used for light cutting, brazing, and certain oxy-fuel operations where moderate glare and radiant energy reduction are required, but full welding shade levels are not necessary. Safety managers frequently search for Shade 5 face shield windows, impact resistant green replacement visors, 8 x 16-1/2 cutting shields, and ANSI face protection components when maintaining fabrication shop PPE inventories. It is important to note that this product is a replacement window component and must be installed on compatible headgear; it is not a standalone welding helmet lens.Sold individually for streamlined maintenance and replacement cycles, the Fibre-Metal 4178IRUV5 helps extend the operational life of existing face shield systems while maintaining consistent performance in high-heat and bright-light environments. Enviro Safety Products is an experienced and trusted supplier of certified PPE, providing authentic Honeywell Fibre-Metal face protection solutions backed by industry expertise to help organizations uphold OSHA-aligned safety programs and dependable workplace protection standards.
