The Anderson Knob Wrap is offered for those of you who prefer a larger diameter knob than the Anderson bats are equipped with. This durable, yet flexible, piece of molded polyurethane stretches over your stock Anderson bat knob, which measures 1 5/8-in, and extends it a 1/4-in to a diameter of 1 7/8 in. The Knob Wrap fits tightly to the stock knob eliminating the need to apply tape or an adhesive.
