Tompkins Gage'T Video
Designed to measure the wall thickness of bowls up to 20" in diameter, the Tompkins™ Gage'T Thickness Gauge is also ideal for checking platters too. The Gage'T frame is made from durable glass-filled nylon and features a spring-loaded measuring rod with etched thickness scale (1/16" increments) and non-marring brass contact points. The distance between the exterior brass ball and caliper indicates the thickness. Gage'T has a 9" reach and can measure up to 2" thick.
