Protect your welding helmet lens with the Weldmark WM320001 2" Twist-Lock Replacement Lens Cover. This clear replacement cover lens is designed for compatible Weldmark helmets that use a 2-inch twist-lock style lens retention system, helping shield the filter lens from sparks, spatter, scratches, and welding debris. Replacing damaged or heavily scratched cover lenses helps maintain clear visibility and extends the life of the auto-darkening or passive filter lens behind it. Always verify your helmet model and lens size before ordering.
