DeWalt Foam Ear Plugs offer heavy-duty NRR 33 protection from sound. That makes these disposable foam ear plugs ideal for high to extreme noise environments -- which is exactly the kind of tough, get-it-done protection you would expect from DeWalt.
Features soft, slow-recovery foam in a popular, tried-and-true bell shape. Just roll down, insert, and hold in place with a fingertip for a few seconds while the foam expands to completely and comfortably fill the ear canal. As with all foam ear plugs, proper insertion is the key to getting the really excellent NRR 33 protection these DeWalt ear plugs provide.
