3M 90563H1-DC Folding Earmuff Nrr 25 Db 5 Pack

Product Description

The 3M 90563H1-DC is an adjustable, folding earmuff designed to protect workers from noise levels at or exceeding 85 decibels. With a Noise Reduction Rating (NRR) of 25 dB, this unit provides reliable hearing protection in loud jobsite environments. The earmuff features padded black cups for all-day wearing comfort and a lightweight construction that reduces fatigue during extended use. It is reusable and built for repeated deployment across multiple shifts or job sites. The folding design collapses the unit into a compact form for straightforward storage in a tool bag or locker.

This earmuff is suited for use in residential and light commercial construction, HVAC mechanical rooms, electrical panel work, plumbing rough-in, and any trade environment where sustained or intermittent high-noise exposure is present. It is appropriate wherever ambient noise levels reach or exceed 85 dB, including generator operation, power tool use, and machinery-heavy environments. This listing includes a pack of 5 units, making it practical for outfitting a small crew or maintaining a supply on a service truck.

Installation Notes

Earmuffs should be fitted by a qualified safety supervisor or worn according to site-specific hearing conservation program requirements. Ensure the cups form a complete seal around the ears before entering a high-noise area. Inspect the cups and headband for wear or damage before each use, and replace if the seal or cushioning is compromised. Hearing protection selection should comply with applicable OSHA 29 CFR 1910.95 noise exposure standards.
