The only arc protection earplugs with Hear-Through earplug design that allows workers to hear conversation, signals, and other critical sounds clearly. If an arc flash occurs, the calibrated noise filter activates immediately to suppress the noise to a lower level - without dangerous delay - reducing the chance of hearing damage and concussive disorientation.

Plus, with double-end versatility, workers just have to insert the plug's red end for protection against exposures to continuous hazardous noises.

Material successfully tested for ARC exposures of category 2 and higher, ASTM F1959-2005 modified.

10 pairs per case.
