33 dB NRR Disposable Foam Corded Ear Plugs, 100-Pair Box

Details Made from a soft, PVC-free polyurethane foam, these protective disposable earplugs have been tested in accordance with ANSI Standard S3.19-1974 and achieved a 33 dB Noise Reduction Rating. Their flared bell shaped end helps guide the plug during insertion and prevents the plug from being inserted too deep into the ear canal. Each plug is tethered to the other with a PVC-free polypropylene plastic cord.. The high contrast orange color provides improved visibility. Packaged in pairs, they come in a convenient 100-Pair dispenser box.
