The RADNOR 64005026 Glass Filter Plate is a passive welding lens filter plate designed for welding helmets and face shields that accept a 4-1/2" x 5-1/4" lens. It uses heat-treated shade 9 glass for eye protection during medium-duty welding and cutting applications.

• Heat-treated glass construction for thermal resistance and durability.
• Standard 4-1/2" x 5-1/4" format fits many traditional welding helmets.
• Shade 9 lens suitable for moderate amperage welding applications.
• Scratch-resistant rigid glass compared with disposable polycarbonate lenses.
• Designed for passive welding helmets rather than auto-darkening systems.
• Low-cost replacement lens option for industrial welding operations.
