Bacou-Dalloz Hearing Safety Group (www.hearingportal.com) has introduced the Howard Leight LS-400 Leight Source plastic dispenser for earplugs. Designed for wall mounting or tabletop use, the unit dispenses 400 pair of earplugs with a twist of the dial. The company says purchasing bulk dispenser refills eliminates packaging waste and saves up to 10 percent on earplug cost. The dispenser includes snap-in rubber feet for tabletop applications.
