Faithfull Inside Spring Calipers

Manufactured from high quality carbon steel with a polished finish. The legs are made from carefully selected flat stock with heat treated points, for durability, and they pivot on a roller while the bow spring ensures a precise tension setting. Accurate adjustments are made by turning the knurled nuts on the threaded rod. The design of these calipers, with their fine adjustment feature, ensures quick and positive setting when taking or transferring specific measurements.
