Architects’ and Engineers’ Scales

Take measurements off of scaled architectural or engineering drawings with these specialized scales.

Dimensional Measuring

Certified High-Accuracy Rulers

These rulers include a certificate of calibration traceable to NIST with test measurements that confirm accuracy.

Stanley Heavy Duty
PowerLock Tape Measures

All have a durable cast metal case that’s chrome-plated for corrosion resistance

Transparent Rulers

Keep your workpiece in view as you measure with these see-through rulers.

Lufkin High-Visibility Tape Measures

A bright orange case makes these tape measures easy to spot.

Pocket Tape Measures with
Corrosion-Resistant Blade

The blade on these tape measures is chrome-plated for durability and corrosion resistance.

Corrosion-Resistant
Stainless Steel Rulers

Made to last, our most corrosion-resistant rulers are stainless steel and have wear-resistant etched markings.

Adhesive-Back Vertical Rulers

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

Scratch-Resistant
High-Accuracy Rulers

Protect your ruler from scratches and wear with a TiN (titanium nitride) coating.

Folding Rulers

Fold these rulers for convenient storage and transport.

High-Accuracy Rulers

An economical alternative to Starrett High-Accuracy Rulers, these provide reliable, repeatable measurements.

Easy-to-Read High-Contrast Rulers

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

Starrett Certified
High-Accuracy Rulers

Ensure reliable, repeatable measurements with these rulers.

Lufkin Tape Measures

These tape measures have a chrome-plated, impact-resistant plastic case.

Lightweight Aluminum Rulers

Made of aluminum, these rulers are an economical alternative to stainless steel rulers.

Diameter Tape Measures

Also known as tree tapes, wrap these tape measures around circular items to determine diameter and measure circumference without the need for calculations.

Certified Lightweight Aluminum Rulers

Ensure accurate measurements with these certified rulers.

Starrett High-Accuracy Rulers

Also known as machinists’ rules, these rulers ensure reliable, repeatable measurements.

Digital Tape Measures

No need to squint at graduation marks with these tape measures—you can clearly read an accurate measurement on the digital display.

Certified Corrosion-Resistant
Stainless Steel Rulers

A calibration certificate traceable to NIST with test measurements that confirm accuracy is included with these stainless steel rulers.

Long-Length Tank-Level Rulers

Connect continuous segments to create a ruler up to 10 ft. long.

Easy-Carry Long Tape Measures

Hold on to the large, rubber-coated handle while carrying these tape measures.

Combination Squares

Starrett High-Accuracy
Combination Square Blades

Use these blades with Starrett High-Accuracy Combination Square Heads. They meet Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

High-Accuracy Combination
Square Blades

Blades are for use with High-Accuracy Combination Square Heads.

Starrett High-Accuracy
Combination Squares

Replace your try square, miter square, depth gauge, height gauge, center-point finder, and level. The blade on these squares meets Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.
