Experience precise angle measurement with the Plastic Angle Rule Goniometer. This compact tool delivers reliable performance in a 6-inch footprint, making it ideal for tight workspaces, classroom demonstrations, or field tasks where accuracy matters. Its 360-degree protractor design enables measurement and angle transfer in any orientation, giving you full control over layouts, joints, or reference angles. Constructed from durable plastic, the instrument combines lightness with resilience for everyday use. The broad operating arms stabilize the tool against workpieces and baselines, helping to minimize movement during measurement. Readings span from 0° to 180° in either direction, with increments marked every 5 degrees for quick estimation and precise documentation. The absence of heavy metal parts reduces fatigue during repeated checks, while maintaining a robust structure suitable for workshop, classroom, or job-site tasks.

Key features

• 6-inch total length with broad arms for stability.
• 360-degree goniometer with measurements in all directions.
• 0° to 180° in each direction, with 5° increments for rapid estimates.
• Dual linear readings in inches and centimeters for easy cross-checks.
• Clear, easy-to-read markings that support fast alignment.
• Lightweight and durable plastic construction that resists corrosion.
• Versatile tool suitable for woodworking, metalworking, engineering, and education.
• Imperial and metric scales enable seamless documentation with drawings or CAD references.

In practical use, align one arm with a baseline, rotate the opposite arm to the desired angle, and read the measurement on the dual-scale protractor. The 5-degree graduation provides quick, repeatable estimates, while the 0–180-degree range in both directions ensures you can capture acute and obtuse angles without reorienting the tool. This makes it well-suited for tasks such as laying out joints, transferring angles from drawings, or validating bent components. The tool supports a wide range of applications—from carpentry and tile setting to light metal fabrication and classroom demonstrations—without the bulk of metal gauges. Its straightforward design makes it an effective teaching aid for geometry lessons, helping students visualize angle relationships and the transfer of angles between lines and surfaces.

Specifications and compatibility

• Material: durable plastic for lightweight handling and corrosion resistance.
• Total length: 6 inches.
• Angle range: 0° to 180° in both directions (360-degree protractor).
• Graduations: 5-degree increments.
• Scales: dual imperial (inches) and metric (centimeters).
• Applications: woodworking, metalworking, engineering, education, and general layout tasks.

Care and maintenance

• Wipe with a soft cloth to remove dust and residue.
• Avoid excessive bending of the arms to preserve alignment accuracy.
• Store flat when not in use to protect the measurement surfaces.
• Clean with mild soap if needed; ensure no harsh chemicals contact the scales.

This plastic angle rule goniometer provides dependable performance for precise angle measurement in a compact, user-friendly design. It combines stability, dual-scale readability, and versatile application across workshop, classroom, and field environments, making it a practical addition to any measurement toolkit.
