Our Concrete Vibrator Head is designed to produce high amplitude vibrations to remove air pockets from the concrete and evenly distribute an aggregate, resulting in higher quality concrete. The Concrete Vibrator Head is for use with our MX FUEL™ Backpack Concrete Vibrator or MX FUEL™ Concrete Vibrator. Our Concrete Vibrator Heads are available in 1", 1-1/4", 1-1/2", 1-3/4", 2" and 2-1/2" sizes.
