4-1/2" x 5-1/4" Shade 10 Heat-Treated Glass Welding Filter Plate

Reliable Protection for the Daily Grind

When you are under the hood all day, your vision is your most valuable tool. The Generic Shade 10 Glass Filter Plate is a no-nonsense replacement lens designed for welders who rely on large-window helmets. Sized at 4-1/2" x 5-1/4", this lens fits a wide range of standard "big window" hoods, allowing you to swap out scratched or damaged filters quickly and get back to work. A Shade 10 is the versatile workhorse of the welding world, perfect for most general fabrication tasks, structural steel welding, and maintenance repairs.

Why choose glass? In a world of high-tech plastics, heat-treated glass still holds its ground for one simple reason: clarity. Plastic lenses can sometimes introduce subtle distortions or haziness over time. This glass filter plate offers a crisp, high-definition view of the weld puddle, helping you control your travel speed and bead profile with precision. The heat-treatment process adds a layer of durability, allowing the lens to withstand the thermal cycles of welding without losing its shape or optical properties.

This passive lens is always on, meaning you never have to worry about being "flashed" due to a blocked sensor or a dead battery. It provides constant, 100% protection against ultraviolet and infrared rays, regardless of whether an arc is struck. It is the ultimate backup lens to keep in your toolbox or the primary lens for welders who prefer the simplicity of passive technology.

Installation Tip: Remember that while this glass lens handles heat and scratches well, it is not impact-rated on its own in the same way a safety shield is. Always install this filter plate behind a clear polycarbonate cover lens and in front of a clear safety plate (closest to your eyes). This "lens sandwich" ensures you meet safety regulations while protecting your filter plate from spatter and smoke, extending its life significantly.
