North 4178IRUV3 Welding Window Shade 3 8x16.5 in

Product Description

The NORTH 4178IRUV3 is a Shade 3 welding window designed for use with compatible face shield brackets and cap systems. Measuring 8 inches high by 16.5 inches wide and 0.06 inches thick, this green-tinted polycarbonate window filters arc and weld flash at a Lens Shade 3 rating. The scratch-resistant coating extends service life in demanding shop and field environments. It meets ANSI Z87.1+ and CSA Z94.3 standards, making it a compliant replacement for face shield assemblies used by welders, fabricators, and maintenance professionals.

This welding window is intended for use as a replacement screen in face shield systems that require an 8-inch by 16.5-inch window. It is suited for both production welding environments and intermittent MIG, TIG, or light arc work where Shade 3 filtration is appropriate. Licensed welding professionals and shop technicians performing routine face shield maintenance will typically specify this part for scheduled screen replacement.
