3M Speedglas Welding Helmet Accessories - Outer Lense

3M™ Speedglas™ Outer Protection Plate 9000, 426000 is standard sized replacement protection plate for 3M™ Speedglas™ Welding Filter Series 9000/9002. Replace original protection plate if it becomes pitted or scratched, with 3M™ Speedglas™ Outer Protection Plate 9000, 426000. Outer protection plate replaces worn or damaged parts and ensures you maintain the correct level of comfort and protection. When original plate becomes deeply pitted, scratched or too dirty to clean with a soft cloth, it's probably time to replace it. Make it a habit to check equipment regularly for maximum comfort and vision. Failure to use an outside protection plate with the filter voids the warranty if spark or spatter contaminates the glass.
