The steel inertia ring of the RaceSeries models is positively protected against forward and backward movement and has the assurance of bonded rubber to eliminate spinning. Every model has easy to read computer etched timing marks.The new two stage clear over black finish is extremelyresistant to scratching and corrosion. All POWERBOND Race series balancers meet SFI specification 18.1.
