Allen 4131 ULTRX Tapered Foam Plugs Features The Allen ULTRX Tapered Foam Ear Plugs are tested and certified to ANSI S3.19 standards delivering a 32 decibel noise reduction rating that provides meaningful protection in loud environments like shooting ranges and job sites. Crafted from soft flexible polyurethane foam the plugs are shaped with a natural taper that conforms to a wide range of ear sizes for a secure comfortable fit. That tapered shape seals both the outer ear and the inner ear canal which helps maintain consistent attenuation through extended periods of wear. For shooters and workers with sensitive hearing the low profile design allows the plugs to be worn comfortably underneath earmuffs for dual-level protection. Each jar contains 25 pairs giving users an ample supply for repeated range trips job sites or shared use among a group. The plugs insert quickly which keeps them practical for shooters who need to protect their hearing on short notice before stepping up to the line. Their compact portable format makes the jar easy to toss in a range bag or toolbox so a fresh pair is always within reach. Passive protection with no batteries or electronics to maintain keeps these earplugs simple reliable and ready whenever hearing protection is needed.
