Description

Glass gauge used with our feeler gauge set to measure the facing curve on mouthpieces.

When reading mouthpiece facing numbers, this is the gauge that is usually referred to.  It shows the actual mm length times 2.  for example, if the facing is 20mm, the gauge will read 40.   If in doubt of which gauge to buy, buy this one, as most facings are given with this system.
