Professional Grade Electrical Safety at a Glance. Ensure your facility remains safe and up to code with our premium 4"x6" voltage rating labels. Designed specifically for industrial environments where standard small stickers fail, these large-format decals provide the high-contrast visibility required by safety inspectors and maintenance crews. Each label is printed on professional-grade, weatherproof materials with a specialized UV-protective coating. This means whether your panels are located in a high-heat manufacturing floor or exposed to the elements in an outdoor solar array, your safety markings will remain crisp and legible for years. The aggressive permanent adhesive is formulated to stick to the most challenging industrial surfaces, including "orange peel" powder coatings and cold metal. Don't risk fines or workplace accidents with handwritten or low-quality tape. Our labels provide a professional, uniform look to all your electrical installations, from main service disconnects to individual motor control centers.
