North 4199IRUV3 Welding Window Shade 3 Green Face Shield

Product Description

The NORTH 4199IRUV3 is a shade 3 green welding window designed for use in face shield assemblies worn during welding, cutting, and related hot-work operations. The lens measures 19 inches wide and 0.06 inches thick, providing a wide field of view with enough structural rigidity to seat securely in compatible bracket hardware. A scratch-resistant coating extends service life in environments where shields are frequently handled and stored. Lens shade 3 is appropriate for light-duty welding and cutting tasks where lower arc intensity is present. Licensed welding professionals and safety-conscious trades installers are the primary users of this replacement window.

This welding window is suited for use in industrial and commercial environments where face shield maintenance and lens replacement are part of routine personal protective equipment upkeep. It fits directly into several Fibre-Metal bracket systems, making it a practical replacement for operations already running that equipment. The green tint and shade 3 rating make it appropriate for torch brazing, light plasma cutting, and similar low-to-mid intensity applications where full shade 5 or higher lenses would over-restrict visible light.

Installation Notes

Installation is performed by the end user or a safety equipment technician following the face shield manufacturer's lens-swap procedure. Remove the face shield from service before replacing the lens window. Ensure the replacement lens seats fully and evenly into all bracket retaining points before returning the shield to service. Inspect the bracket and frame for cracks or deformation any time a lens is replaced.
