3M™ earmuffs feature durable, lightweight construction of non-conductive, dielectric plastic that mounts to most hard hats without an adaptor and easily swing out of the way when not in use.
- Lightweight, durable plastic construction is non-conductive and dielectric for tough environments
- An "at-rest" position eliminates contact with other gear to reduce contamination and distortion
- Works 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.
