Industrial machinery, roadway maintenance and construction vehicles, manufacturing equipment, recreational vehicles and even concert venues and sporting events can expose your ears to damaging levels of noise. Protect your hearing with a pair of 212 Performance Earplugs. Made from a soft and flexible synthetic TPR rubber, these protective reusable earplugs are designed and engineered with a triple sealing flange shape that creates a positive seal in the ear canal without creating irritating pressure to allow for all day comfort. The bright red color of the plugs’ stems provides improved visibility and helps aid in ensuring workplace compliance. To keep them from being misplaced when used in areas and situations that require them to be removed and reinserted often, each plug is tethered to the other with a PVC-free polypropylene plastic cord. These earplugs have been tested in accordance with ANSI Standard S3.19-1974 and achieved a 27 dB Noise Reduction Rating. Packaged in corded pairs, these one size fits most plugs come in a convenient 100-Pair dispenser box to keep your a crew safe or ensure you will always have a pair when you need one.
