Empire 200mm Inside Spring Calipers

Use the Empire 200mm Inside Spring Calipers to accurately measure the internal diameter of pre-drilled holes, conduit, pipes and round objects. Made from durable carbon steel, these Calipers can withstand tough worksite conditions. A large bearing surface on the fulcrum stud prevents side deflection of the legs. Dimensions for holes/objects can be locked in and then verified using additional measurement tools such as a ruler or micrometer. The Internal Spring Calipers can be used to measure the diameter of pre-drilled holes, verify the width of grooves/slots, check the diameter of pipes and conduit and measure the internal diameter of bearings and bushings.
