3M™ Speedglas™ Outer Protection Plate 9000, 427000 is our scratch-resistant replacement protection plate for 3M™ Speedglas™ Welding Filter Series 9000 and 9002.
Replace your original protection plate if it becomes pitted or scratched, with 3M™ Speedglas™ Outer Protection Plate 9000, 426000. Our outer protection plate replaces worn or damaged parts and ensures you maintain the correct level of comfort and protection. When your 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 your 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.
