Tri-Grip earplugs are one of the most popular solutions in modernday hearing protection. Tri-Grip has an independently tested 27 dB NRR, the highest third-party tested, reusable earplug rating available. With a patented, three-sided stem that provides a stable, comfortable grip, Tri-Grip has become the premium choice for reusable earplugs among workers. This three-sided grip allows workers to insert the plug into the ear without any rolling or touching other areas - providing a more hygienic earplug solution. The Tri-Grip stem also includes a semirigid insert, bonded with adhesive, which allows for easy insertion without too much pressure. Soft, curved flanges further ensure a comfortable fit, helping the plugs conform to the shape of the ear canal. Tri-Grip is also available in Tri-Grip JR, 10% smaller to fit smaller ear canals. Plus, Tri-Grip MD and Tri-Grip MTek offer metal detectable versions.
