"MATRIX Blue"-"No Cord" ear plugs. Made by Howard Leight.|
Part #MTX-1-BU has a Noise Reduction rate (NRR) of 23dB. MATRIX is the only single-use earplug in the world that screens harmful noise out, but lets voice frequencies in. This means workers can hear each other much better on the job, enhancing
communication, safety, and overall compliance. Matrix also
comes in three distinct attenuation profiles, to specifically match
any application. Blue in color, 200 pair per box.
