Angle Indicators

Also known as angle finders, use these to gauge the angle of any surface.

Magnetic-Mount Angle Indicators

Temporarily mount these indicators to a metal surface. They have four quadrants that each read any angle from 0° to 90°.

Heavy Duty Magnetic-Mount Angle Indicators

These angle indicators have a horizontal leveling vial and can measure angles between 0° and 180°.

Dual-Axis Tilt Indicators

Measure 40° front-to-back tilt in addition to side-to-side tilt.

Single-Axis Tilt Indicators

A ball inside a level tube indicates the side-to-side tilt angle.

Digital Angle Indicators with Laser

Align guide rails or lay pipe at specific angles from a flat surface.

Digital Angle Indicators

These angle indicators display highly accurate angle, level, and tilt measurements.

Digital Angle Indicators with Calibration Certificate

These angle indicators come with a calibration certificate that's traceable to NIST and includes the test measurements that confirm accuracy.

Digital Angle Indicators with Pitch Measurement

The LCD on these digital angle indicators shows angle in degrees and percent of slope.

Pocket Digital Angle Indicators

At 2 1/4" square and 1" wide, this angle indicator easily fits into your pocket.

Pocket Digital Angle Indicators with Level

These angle indicators also show level on the display.

Digital Angle Indicators with Remote Display

The electronic sensor and the display are connected by a 4‐ft. cable so you can measure angles from a distance. They can be mounted up to 150 feet apart by replacing the included cable with a longer cable length.

Protractors

Digital Protractors with Level and Laser

A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle.

Digital Protractors with Level

These tools have front and back digital displays, as well as horizontal and vertical vials.

Digital Protractors

These magnetic tools have one digital display and a lock to hold the arms in position.

Precision Protractors

Take precise measurements with this protractor.

Protractors

Measure angles with these round protractors.

Starrett Protractors with Adjustable Arms

Also known as bevel protractors, set bevels and measure angles with the adjustable arm.

Protractors with Adjustable Arms

Set bevels and measure angles. Also known as bevel protractors, these have an adjustable arm.

Mitutoyo Precision Protractors

Precisely measure angles on molds and jigs.

Long-Arm Protractors

Handle big jobs such as sheet metal fabricating and pipe bending with these long-arm protractors.

Pocket-Size Protractors

Small enough to fit in your pocket, this versatile tool measures angles and dimensions and has a center finder.

Protractors with Graduated Arm

Use these protractors to measure angles and dimensions.

Adhesive-Back Protractor Dials

Mount on any flat surface.

Starrett Protractors with Graduated Arm

Measure angles and dimensions with one tool.

Angle Identifiers

These gauges have 18 leaves that swing out when you want to quickly check an angle. They're more convenient than a protractor when identifying 45° and smaller angles.

Combination Squares

High-Accuracy Combination Square Heads

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

High-Accuracy Combination Square Blades

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

Combination Squares

Replace your try square, miter square, depth gauge, marking gauge, 90° level, ruler, and scriber with one tool.

High-Accuracy Combination Squares

Use these squares in place of your try square, miter square, depth gauge, height gauge, center-point finder, and level.

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.

Scratch-Resistant High-Accuracy Combination Squares

A titanium coating protects the blade against scratches and wear.

Starrett High-Accuracy Combination Square Heads

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

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.
