Combination Squares
Replace your try square, miter square, depth gauge, marking gauge, 90° level, ruler, and scriber with one tool. Blades labeled with numeric increments that are less than 1" are quick-reading. All have wear-resistant etched markings.
Square head checks 90° angles.
Center head identifies the center on pipes, rods, and shafts.
Protractor head measures angles.
Angle finder measures any angle from 0° to 90° and has a chart to convert angle to pitch.

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. Blades are labeled with numeric increments that are less than 1" for quick reading. All have wear-resistant etched markings.
Square head checks 90° angles. Center head identifies the center on pipes, rods, and shafts.
Satin-chrome blade finish is corrosion resistant and reduces glare. Hardened-steel heads are more durable and last longer than cast iron heads.
