SparkPlugs also come in a metal detectable version which has a new metal detectable cord. The bright blue color is perfect for food processing applications. The enclosed metal ball bearing eliminates any exposed metal. The ball bearing and cord are in separate holes so that the ear plugs remain detectable even if the cord is removed. The ear plugs are corded to prevent ear plug loss.
