Featuring the Patented Cert-A-Fit® Technology — Creating The New Standard for Foam Earplug Fittings.

Sert-A-Plug delivers consistent insertion of foam earplugs through a standardized mechanical action, making foam earplugs easier and faster to fit reliably.

Sert-A-Plug delivers consistent insertion of foam earplugs. In controlled fit-test studies, users have achieved an average measured Personal Attenuation Rating (PAR) of approximately 29 dB when foam earplugs are inserted with the Sert-A-Plug applicator. PAR is a personal measurement; individual results will vary based on ear anatomy, plug selection, and insertion technique. The foam earplug carries the Noise Reduction Rating (NRR) per the manufacturer’s existing EPA-regulated label.
