The earcups are molded in bright orange ABS for high-visibility identification on busy job sites. A stainless steel headband resists bending and warping under repeated daily use. Liquid and foam filled cushions seal around the ear to achieve a Noise Reduction Rating of 23 dB, and earcup pivot points tilt to accommodate a range of head sizes. Licensed electricians, HVAC technicians, plumbers, and other trades workers install and use this type of PPE wherever power tools, generators, or mechanical equipment push ambient noise above safe thresholds.\u003c\/p\u003e\n\u003cp\u003eThis earmuff suits residential and commercial construction, mechanical rooms, and industrial settings where over-the-head wear style is required or preferred. The bright orange cups make the wearer easily identifiable as wearing hearing protection, supporting site compliance documentation. The lightweight design allows all-day wear without excessive fatigue. No hard hat or face shield adapter is included; this unit is configured for standard over-the-head use only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e23 dB Noise Reduction Rating (NRR) with CSA Class A certification\u003c\/li\u003e\n  \u003cli\u003eBright orange ABS earcups for high-visibility identification\u003c\/li\u003e\n  \u003cli\u003eStainless steel headband construction resists bending and warping\u003c\/li\u003e\n  \u003cli\u003eEarcup pivot points tilt for optimum fit and acoustic seal efficiency\u003c\/li\u003e\n  \u003cli\u003eLiquid and foam filled cushions provide a comfortable, all-day seal\u003c\/li\u003e\n  \u003cli\u003eLightweight design reduces fatigue during extended wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an over-the-head hearing protector for general industrial and trade use where standard earmuff PPE is required by site safety programs or OSHA noise exposure regulations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required; fit by extending the headband until the earcups seat flush and symmetrically over both ears. Per OSHA 29 CFR 1910.95 and equivalent standards, the NRR should be derated when estimating real-world attenuation -- 3M recommends applying a 50 percent derating to the labeled NRR for typical use conditions. Inspect cushions and headband for cracks or compression set before each use, and replace worn cushions promptly to maintain rated attenuation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoise Reduction Rating (NRR)\u003c\/strong\u003e: 23 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: CSA Class A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWear Style\u003c\/strong\u003e: Over-the-Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEarcup Material\u003c\/strong\u003e: ABS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeadband Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCushion Type\u003c\/strong\u003e: Liquid and Foam Filled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEarcup Color\u003c\/strong\u003e: Orange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.94 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 19.61 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 10.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 07318640051645\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000141055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346144428338,"sku":"7000141055","price":542.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310513664.jpg?v=1782072024","url":"https:\/\/voomisupply.com\/products\/3m-7000141055-over-the-head-earmuffs-24-db-nrr","provider":"Voomi Supply","version":"1.0","type":"link"}
