EASY TO USE

To use, clamp the blades so that the zero marks meet at the V. Place the caliper astride a round object and read the outside diameter and NPT pipe size where the scales touch the object. On one side the scales are graduated 0 to 6” O.D. and 0 to 5” NPT. On the flip side the scales are 0 to 13” O.D. and 0 to 12” NPT.
