Description The 527000 3M Speedglas 9100 Outer Lens is scratch-resistant comes in a packet of 10 and protects the inside surface of your welding filter from sparks and spatter. The extra scratch-resistant replaces worn or damaged parts and ensures you maintain the correct level of comfort and protection. Designed for 3M Speedglas welding filter series 9100. Use as a replacement when your original plate becomes deeply pitted, scratched, or too dirty. We recommend you regularly clean it with a soft cloth and replace it when pits or scratches occur for maximum comfort and vision. This scratch-resistant model may extend service life compared to the standard model. Failure to use an outside protection plate with the filter voids the warranty if sparks or spatter contaminate the glass.
