Choose the Correct Fit
Confirm the earmuffs fit your exact Milwaukee hard hat or safety helmet. Check clearance with other BOLT accessories before use.
Select hearing protection for the measured noise exposure. Eyewear, hair or other PPE must not interfere with the ear-cushion seal.
Installation & Care
Seat the mounts in the designated slots and adjust the cups to cover both ears fully. Use storage positions only outside hazardous noise.
Inspect cushions, mounts and arms before use. Clean and replace worn parts according to the earmuff instructions to preserve the seal.

Important Product Questions
Which head protection can these mount to?
Milwaukee certifies these earmuffs for its safety helmets and hard hats. They secure in the BOLT and universal accessory slots; verify the exact configuration with other fitted accessories.
Where can the cups be stored when not in use?
The rotating arms allow positions at the back, top or below the brim. Return the cups to a full ear seal before entering hazardous noise.
Will I always get 24 dB of noise reduction?
No. The 24 dB NRR is a laboratory rating. Actual protection depends on fit, cushion seal, consistent use and the noise exposure.
