Howard Leight SmartFit® Ear Plugs

Designed for processing industries, this detectable earplug features advanced material that uses body heat to adapt to the shape of each individual’s ear canal. Blue color provides high visual detection, and detectable ring on the stem and attached cord can be detected by automated equipment. Triple-flange distributes pressure evenly.
Tested to ANSI S3.19-1974. CSA Class AL.
NRR is the Noise Reduction Rating in decibels (dB). It is the average noise reduction obtained by a group of people wearing a specific hearing protector in a laboratory test. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit and and wearing time. It is recommended that the NRR be reduced by 50% for estimating the average amount of noise reduction provided.
