Reliable, spring-loaded covers effectively seal front panel bushing openings from dust and dirt when mating plugs are not connected to jack. Series 500 is mounted with conventional threaded bushing jacks. Special locknut (comes with Series 500 jack covers) seals tightly against rubber washer when cover is closed. Series 600 is used with certain type tip jacks. Due to variable jack dimensions, two .031 inch washers are supplied.
