J3 Group LLC was founded in 2008 by Confederated Tribes of Siletz Indian Elder and Occupational Safety & Health expert John Johnson with sons Joshua and Shawn.
Sert-A-Plug was inspired with the goal of mitigating occupational Noise Induced Hearing Loss. Father and sons designed, patented, and developed Sert-A-Plug® as a high-quality State-of-the-Art earplug insertion tool for the occupational worker.
Patented Sert-A-Plug® earplug insertion tools are uniquely designed to fit directly into the ear canal for an accurate fit and to provide the highest Personnel Attenuation Rating (PAR) when compared to the uncertainty of traditional finger fitting.
