This package contains 2 genuine Eureka "Style U" flat upright belts. One belt is used at a time although it should be changed at least once per year to keep the cleaner performing well. These belts are for all Eureka uprights in the 4100-4600, 5180, 5190, 7600-7900 and 9000 series. They have been replaced by the Eureka "Style U" Extended Life Belts #61120 which last up to two times longer.   For similar products see our list of current Eureka Vacuum Supplies. Show Less
