High-Accuracy Rulers
Inch
Inch/Metric
Metric
An economical alternative to Starrett High-Accuracy Rulers, these provide reliable, repeatable measurements. All meet Fed. Spec. GGG-R-791H, which establishes uniform standards for ruler accuracy, graduations, and size. They're also known as machinists' rules. They have a corrosion-resistant satin-chrome finish that reduces glare and wear-resistant etched markings. Inch and inch/metric rulers are labeled with numeric increments that are less than 1" for quick reading.
Flexible rulers are for measuring slightly curved surfaces.

Inch and inch/metric rulers are labeled with numeric increments that are less than 1" for quick reading.
Flexible rulers are for measuring slightly curved surfaces.
