This Caliper is intended to measure inside diameters from 1 inch to 2
inches by thousandths of an inch. It is constructed the same as the No.
101 but is a larger instrument with two interchangeable screws, one measuring from 1 inch to 1-1/2″ inches and the other from 1-1/2″ inches to 2 inches. This caliper is provided with a handle so that measurements can be taken throughout the entire length of a bore.
