You pull the legs apart to open the thickness caliper, then adjust the spacing nut to set the wall thickness you want before checking it against the workpiece.
The 9" model adjusts from 0" to 5 1/2", and the 16 1/2" model adjusts from 0" to 13 1/2", so the larger caliper handles deeper vessels and bowls.
Yes, it works well for dimensional take-offs on almost any oddly shaped object, not just turned bowls and vases.
It's made of steel with brass fittings for the spacing nut and legs.
