Honeywell Howard Leight Laser Trak LT-30s are the most popular metal detectable earplugs on the market, and for good cause: every feature is made to reduce the risk that earplugs contaminate the food. The embedded ball bearing ensures the plugs are picked up by metal detection systems, and the bright blue and orange colors make visual detection a breeze.
The cord keeps the plugs close to the operator's body, and the very soft polyurethane foam slowly expands to create a tight, comfortable fit for all-day use. Noise Reduction Rating: NRR 33dB. If you are looking to reduce the risk of contamination from your earplugs, these are a proven choice.
Sold in boxes of 100 pairs. Compare with Moldex SparkPlugs, or see the full range of metal detectable ear plugs.
