Description
3M 330-3031 E-A-R 2000H Ear Muff
Cap Mounted NRR 21
The 3M 330-3031 mounts to most hard hats. Lightweight, durable plastic construction is non-conductive and dielectric for tough environments. Muffs swing up and out of way quickly. "At-rest" position eliminates contact with dirty hard hats, reduces contamination and cushions distortion. Works with H20 AO Tuffmaster® face protection system. Cups are interchangeable with the Model 1000. Laboratory tested NRR 21dB. Canadian Class Code B.
