Lee Valley Stainless-Steel Tracing Profile Gauge

With nearly twice as many fingers per inch (26 versus 15) as plastic models, this 7″ gauge gives you smoother curves and finer details (but does not work as well on things like cross sections of smooth cylinders).

The stainless-steel fingers are held firmly in the steel bar. Profiles can be taken up to 3 1/8″.

An excellent gauge. Made in Japan.
