3M 7100009551 Speedglas 100 Outside Protection Plate

Product Description

The 3M 7100009551 is an outside protection plate designed for the Speedglas 100 series welding helmet. This standard-type replacement lens plate mounts on the exterior face of the helmet shell to shield the auto-darkening filter from spatter, grinding debris, and arc flash exposure. Keeping the outer lens clear is critical for maintaining proper optical clarity and filter performance. This part is sold as a case of 10 plates, making it a practical stocking item for shops and fleet service accounts that run multiple welding helmets. Installation requires no special tools and is a routine consumable replacement task.

Outside protection plates are consumable components intended for regular replacement as part of standard helmet maintenance. The Speedglas 100 series is used in light industrial, fabrication, MIG, TIG, and stick welding applications across residential and commercial trade environments. Replacing worn or scratched outer lenses restores full visibility through the helmet and extends the service life of the auto-darkening filter assembly underneath. This plate is the standard size matched to the Speedglas 100 helmet form factor.
