102 Products

Protractors with Adjustable Arms

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

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 Graduated Arm

Use these protractors to measure angles and dimensions.

Starrett Protractors with Graduated Arm

Measure angles and dimensions with one tool.

Precision Protractors

Take precise measurements with this protractor.

Mitutoyo Precision Protractors

Precisely measure angles on molds and jigs.

Pocket-Size Protractors

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

Adhesive-Back Protractor Dials

Mount on any flat surface.

Long-Arm Protractors

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

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.

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.

Angle Indicators

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.

Digital Angle Indicators with Laser

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

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.

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°.

Angle Indicators

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

Heavy Duty Magnetic-Mount Angle Indicators

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

Single-Axis Tilt Indicators

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

Dual-Axis Tilt Indicators

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

Combination Squares

Scratch-Resistant High-Accuracy Combination Squares

A titanium coating protects the blade against scratches and wear.

Combination Squares

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

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.

High-Accuracy Combination Squares

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

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.
