A calibration certificate traceable to NIST with test measurements that confirm accuracy is included with these stainless steel rulers. They're flexible for measuring slightly curved surfaces and have wear-resistant etched markings.

Numbers and graduations etched in light colors are easy to see on a black background.

Aluminum rulers are lightweight and corrosion resistant.

Flexible rulers are for measuring slightly curved surfaces.

Rulers have large numbers and deeply etched graduations. All are flexible for measuring slightly curved surfaces.

A cork back prevents slipping and protects delicate surfaces. Rulers are corrosion-resistant stainless steel and have wear-resistant etched markings. All are flexible for measuring slightly curved surfaces.

A clear protective coating and brass endcaps add durability to these hard-maple rulers. They have wear-resistant etched markings.

Made of wood with a clear protective coating, this ruler is an economical choice for measuring objects up to three feet long. It has metal endcaps for durability.

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.

Permanently mount these rulers to a machine or workbench.

Flexible rulers are for mounting on curved surfaces.

Use to find diameters and centers. The graduations and numeric increments on these rulers are half the actual length of the object you are measuring; a 1" graduation is actually 1/2", a 2" graduation is actually 1", and so on. All are flexible for mounting on curved surfaces.

Permanently mount these rulers on machines, tanks, and walls to measure heights and depths.

Measurements are printed from top to bottom for measuring heights and depths. These aluminum rulers are lightweight and corrosion resistant.

Zero marks the center when these rulers are positioned so the same number touches each side of an object. All are corrosion-resistant stainless steel and have wear-resistant etched markings. They're flexible for measuring slightly curved surfaces.

Determine the circumference of a circle without calculations. These rulers have an inch scale for measuring diameter on the top edge and the corresponding circumference scale on the bottom edge. They’re also known as tinners' rules. All are flexible for measuring slightly curved surfaces and have wear-resistant etched markings.

Slide the lock to hold the blade in place. The case is chrome-plated, impact-resistant plastic.

Lacquer-coated blades are corrosion resistant.

Attach to curved or flat steel surfaces.
