Laser track foam earplugs offer high visual and metal detectability in a single-use earplug. Their low-pressure polyurethane foam expands gently inside the ear canal for comfortable long-term wear, while its contoured t-shape delivers easy handling. A enclosed metal grommet in the earplug aids in metal detection, especially in process industries. These earplugs have an NRR of 32Db and are easily visually spotted by their bright orange and Blue colors. 100 pairs per dispenser
