Convex Ruler

Measure curves and rounded edges accurately.

• Reads measurements on curved surfaces easily
• Stays in place on non-flat work
• Saves time on repetitive radius checks

A convex ruler is designed to measure curved and rounded surfaces where a straight ruler won't sit flush. Whether you're checking pipe diameters, verifying arc radii, or working with cylindrical parts, this tool gives you fast, reliable readings. Useful for metalworkers, machinists, fabricators, and anyone dealing with curved dimensions on the job.
