See-Thru welding curtains are made of heavy-duty, translucent vinyl to provide excellent protection from the U.V. radiation and blue light generated from welding activities. Curtains are made to size, with hems turned on all four sides. Grommets are positioned on 8" centers across the top and on 16" centers on both sides. Gold See-Thru curtains are formulated to disperse light from welding arc throughout the curtain while creating a bright work area. Recommended for low to medium amperage welding applications. Green See-Thru curtains are the preferred choice when light from welding activity needs to be darkened for surrounding workers. Recommended for medium to medium-high amperage welding applications.
