Extreme Vibration Mounting Kit

The Extreme Vibration Mounting Kit protects NEWMAR power converters from the extreme stresses of shock and vibration when mounted on high-vibration vehicles. This kit replaces the standard vibration kit provided with the unit and fits into the unit’s mounting flange, acting as a ‘super shock absorber’ for electronics in high-vibration applications.
