LARGE RUBBER ACTIVATOR
This Large Rubber Activator has a large, stable base. It sits on any flat surface, or in the palm of your hand. It is the perfect softness of rubber to activate the sound without damaging the fork or interfering with the vibrations. We don't recommend hockey pucks for this reason - the rubber is too hard.
Size: 3 Inches Long x 3 Inches Wide x 1.8 Inches High
