3M™ Peltor™ Optime™ 105 Red/Black Behind-The-Head Earmuffs with 29 dB NRR feature double-shell technology to provide effective hearing protection. They offer maximum noise reduction throughout the full range of low and high frequencies. ABS earmuffs with stainless steel headband and liquid/foam filled cushions distribute weight for low-pressure fit while the pivot points tilt for optimum comfort and efficiency. They can take the noise levels up to 105 dBA and are developed to provide ultimate protection in the most demanding noise environments. They are color-coded to help match attenuation needs. Application areas include assembly, cleaning, demolition, electrical, grinding, machine operations, painting, sanding and welding. Earmuffs are suitable for industries like automotive, construction, food and beverage manufacturing, manufacturing, metal production and fabrication, military maintenance, repair and operation, mining, oil and gas, pharmaceutical and transportation.
