Extra Rubber Feet: Our Rubber Feet are high quality solid rubber feet, they grip and do not vibrate or squeak around. These feet have a lifetime warranty with our cabs. These are standard for all of our Cabs. These are 1 1/2″ in diameter and 5/8″ thick.
The Extra Rubber feet option is so that you can have a set of feet on the left or right side of your cab so you can stand it up vertically. All of our cabs ship with rubber feet on the bottom.
