DEWALT DPG66-D Cap-Mount Interceptor Earmuff NRR 26dB, Black/Yellow

I bought a couple sets of these for my truck drivers that have pickups at noisy plants. They fit into their hardhats perfectly. My guys have come back to me and said they were perfect! Cut out the noise and the fit was comfortable! They love them!

These were easy to get onto my hard hat and functioned very well for about 4 years until they started breaking. I'm especially rough on things, so that's not a bad run. I use to work outdoors next to drilling rigs in frigid Wyoming winters with wind chill factors below -20F. On days like that, these functioned very well as a dual purpose accessory: warmth and hearing protection.

fit well on climbing helmet

Love them I used them on my arborists helmet I was making . Works out with just a little Modification

Didn't like these made the hard hat not sturdy and even while wearing
