Measure depths up to 8" using connectable extension rods.

All gauges have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off.

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Take precise depth measurements in small holes and slots.

Increase the base width of your depth gauge to measure large diameter holes.

Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Fold these vertical rulers for convenient storage and transport.

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

Measurements are printed from top to bottom for measuring heights and depths.

Create a ruler up to 192" long by adding continuous segments.

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.

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.

Attach to High-Accuracy Combination Square Blades with the included lockbolts.
