Glass welding helmet Cover Lens 2' x 4 1/4'

Glass Welding Helmet: This indicates that the protective lens is specifically designed to be used with a welding helmet. Welding helmets are worn by welders to protect their face and eyes from intense light, sparks, and debris generated during welding.

Cover Lens: The protective lens is commonly referred to as a "cover lens." It serves as a shield to protect the primary viewing lens of the welding helmet from damage, such as scratches, spatter, and debris. The cover lens can be replaced when it becomes worn or damaged, extending the life of the helmet.

2' x 4 1/4': This measurement specifies the dimensions of the cover lens. In this case, the cover lens measures 2 feet (24 inches) in width and 4 1/4 feet (approximately 51 inches) in height. These dimensions ensure that the lens adequately covers the viewing area of the welding helmet, providing protection for the welder's face and eyes.
