Thunder Noise Blocking Earmuffs
Thunder series earmuffs have a dielectric construction to protect workers in electrical environments. They are designed with all-day comfort in mind. The headband earmuffs feature a unique dual-headband for better positioning and breathability, and non-deforming outer headband that minimizes pressure on the head. The Cap-Mounted styles can be used with a wide range of hard hats. Inner-ventilated headband minimizes pressure on the head, breathes easier in warm/humid climates [T2 and T3 only]. Earcups snap in place during use and swing back when not in use. They include a pair of adapters for use with popular hard hats. Features patented Air Flow Control technology for optimal attenuation across all frequencies and also snap-in ear cushions for easy maintenance.
