Radius Identifiers
Check Concave Radius
Check Convex Radius
A
B
Measure the radius of curves on tools, patterns, and dies. These identifiers are small enough to carry around.
Style A identifiers check both convex and concave radii.
Use style B identifiers as a radius gauge, diameter gauge, and ruler. They check for convex radii. Made of stainless steel, they resist corrosion.

Precision Radius Identifiers
Find precise convex and concave radii of tools, patterns, and dies.
Identifiers with a NIST calibration certificate include a document stating that they have passed a test for accuracy.
