What is the difference between the KSD-G2 for the CB-2000 and the one for the CB-3000/Curve and the CB-6000?
The KSD-G2 fits partway into the CB-2000/3000/Curve. The opening for the CB-2000 is a bit larger than the one for the CB-3000/Curve. The KSD-G2 is designed to almost snap into the tube of the CB-2000and you put them on together. That will alleviate any pinching of the skin. The KSD-G3 for the CB-6000 will not fit the other CB’s without some modification to the center hole of the G3.
