3M Speedglas Inner Cover Plate 9100V (+1 Shade)
Inner Cover Plate 9100V (+1 shade) 528005
The 3-pack Speedglas +1 shade Inner Cover Plate 9100V is essential for protecting the inside surface of the welding filter from sparks and spatter.
Without an inner protection plate, the warranty will be voided if damage to the glass is caused by sparks or spatter.
It is recommended to regularly clean the plate with a soft cloth and replace it if any pits or scratches occur. Additionally, the plate can be used to increase the +1 dark shade of the welding filter.
