Professional welding lenses for commercial or occasional use. These clear replacement lenses are designed for most standard welding masks and flip-up or reactor light masks. The anti-splatter plastic construction prevents spatter from sticking and offers more durability than glass lenses if dropped. This pack contains 3 lenses. The plastic material allows for cutting down to smaller sizes if needed to protect the darkening element of your auto-darkening welding helmet. Each clear lens comes with a protective strip on both sides to prevent damage or scratching before use.
