Components of CDI's comparator stands can be purchased separately. The indicator arms will accept most manufacturers' gages and are designed to fit on a 1.25" diameter column. The arms can be either lug mount or stem mount, rigid or with a fine adjustment knob. The granite bases have a counterbored through hole to accept a 1/2" diameter bolt. All granite bases come with a Certificate of Accuracy, traceable to N.I.S.T..
