The Moldex 6847 PlugStation is a convenient dispenser for the Mellows earplugs. The unit arrives sealed for hygiene with 500 pairs of Mellows earplugs inside. Simply mount the unit to any wall so workers can conveniently access the dispenser. Place units in all work areas and break rooms and workers will be able to quickly access hearing protection. With the PlugStation, you can eliminate the mess of individually packaged earplugs. A clicking mechanism allows the earplugs to fall directly into your hand. When the unit is empty, simply replace with a fresh dispenser. Mellows earplugs are NRR 30 and ideal for mid to high level noise environments.
