3M 7100329539 Corded Earplugs 50 Pair Per Box

Product Description

The 3M 7100329539 is a corded earplug from the E-A-R UltraFit series, designed for repeated use in industrial, construction, and trade environments where sustained hearing protection is required. Each earplug features a triple-flange design that conforms to a wide range of ear canal shapes and sizes, creating a noise-blocking seal without requiring rolling or insertion force. The body is made from a pliable, soft polymer that can be rinsed and reused, reducing per-use cost over time. Each box contains 50 corded pairs and includes a carry case for storage and transport between job sites.

These earplugs are suited for ongoing use in loud work environments such as mechanical rooms, shop floors, job sites with power equipment, and other settings where workers require dependable hearing protection throughout a shift. The corded configuration keeps both earplugs together when not in position, reducing loss. The washable, reusable design makes them appropriate for tradespeople who need reliable protection across multiple work sessions. Each case pack contains five boxes for a total of 250 pairs.
