3M™ E-A-R™ Model 2000H Earmuffs 330-3031 - Hard Hat Attached

These hard hat ear muffs mount to most hard hats without an adaptor and easily swing out of the way when not in use.

• Lightweight, durable plastic hard hat ear muffs construction is non-conductive and dielectric for tough environments.
• An "at-rest" position eliminates contact with other gear to reduce contamination and distortion.
• Hard hat ear muffs work with most slotted hardhats
• Noise Reduction Rating* NRR 21 dB. CSA class B

  *The NRR may overestimate the hearing protection provided during typical use. 3M™ recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.

  3M™ is Leading the Advancement of Hearing Conservation™.
