Product Information

Full details

The Stanley Line of Chords Rule is a versatile precision measuring tool designed for engineers, students, and drafters who require accurate angular measurement and circumference calculations. Providing a dual-purpose solution for geometry and mechanical layout, this 600mm tool allows users to set or measure precise angles via its integrated chord scale; however, users should note that using this device effectively requires a separate set of dividers to leverage its specific geometric features.

FAQs

What is the maximum angle this rule can measure?

The integrated line of chords scale covers angles from 0° up to 120°.

Does this rule include imperial measurements?

It features a 24-inch length marking, though the primary sub-divisions are in millimeters.

Can I use this for measuring cylindrical objects?

Yes, you can measure the diameter of a cylinder and read its corresponding circumference using the specific scale on the back of the rule.

Are the blades flexible?

The rule is designed for precision drafting and is intended to be used on a flat surface, so it is not designed to bend around curved objects.

Do I need special tools to use the line of chords feature?

Yes, a pair of standard drafting dividers is required to accurately span the distance between points on the scale.

Is the rule made of metal?

Yes, the Stanley Line of Chords Rule is constructed from high-quality durable materials intended for long-term use.

Troubleshooting

Difficulty reading measurements in low light

Ensure the rule is held at a slight angle to allow light to catch the etched markings or use a dedicated task lamp.

Measurements seem inconsistent

Verify that you are using a sharp-pointed set of dividers and that the pivot point is accurately centered on the rule's center dots.

Pros and Cons

Pros

  • Versatile multi-function design combines linear, angular, and circular measurements
  • High-precision 1/2 degree angular increments
  • Dual-sided layout prevents overcrowding of markings
  • Durable construction suitable for professional and classroom environments

Cons

  • Requires external dividers to utilize the line of chords functionality
  • The 600mm length may be bulky for small portable pencil cases
  • Lacks imperial circumference measurement scales

Setup, Compatibility & Care

No complex setup is required for the Stanley Line of Chords Rule; it is ready for use immediately upon removal from the provided display wallet. To maintain the accuracy of the markings, store the rule in its protective wallet when not in use to avoid scratches or edge damage. Clean the rule periodically with a dry, lint-free cloth to ensure the graduations remain clearly visible. Avoid using harsh chemical solvents that could degrade the printed scales. When working, ensure the rule remains flat against the drafting surface to prevent parallax errors during measurement.
