3M 311-4101 Disposable Corded Ear Plugs 33 dB 200 Pairs

33 dB Noise Reduction for Demanding Environments

These disposable foam ear plugs deliver a noise reduction rating of 33 dB, meeting CSA Class AL standards for high-attenuation hearing protection. The cylinder shape and roll-down insertion method suit workers who need reliable, single-use plugs that expand to fit the ear canal. Metal-detectable components and a blue metal cord add safety for food-processing or manufacturing lines where foreign-object detection is mandatory. The yellow colour aids visual compliance checks.

200 Pairs Bulk Supply with Corded Convenience

Each box contains 200 individually wrapped pairs packed in cardboard pillow packs, providing long-lasting stock for daily rotation or team distribution. The metal cord keeps plugs together when not inserted, reducing loss and allowing quick removal and re-insertion during breaks. Because they are disposable, there is no cleaning or maintenance cycle; users simply discard after each shift. The bulk format suits high-turnover sites but may exceed the needs of occasional home users.

Fits Large Ear Canals

Sized large, these plugs target wearers with wider ear canals who find standard plugs loose or uncomfortable. The PVC foam construction and metal-detectable cord and band integrate with metal-detection gates common in regulated production areas. No electronic features, rechargeable elements or reusable frames are present, so buyers seeking Bluetooth connectivity, active noise cancellation or washable options must look elsewhere. The product focuses purely on passive, high-attenuation, single-use protection.
