Howard Leight™ TrustFit® Trak reusable push-in metal detectable earplugs are designed with an ergonomic stem and dimpled foam tip so they are easy to fully insert and remove. Pod-shaped earplugs have a large, ball-shaped foam end that fills the ear canal. A paddle grip pushes the pod into place so there's no need to touch or roll the earplug, making it a good choice for dirty environments. An extension of the TrustFit® Family when contamination is unacceptable. Designed for process industries such as food and beverage and paper and pulp, TrustFit Trak Metal Detectable earplugs provide all day comfort.
