FAQs
What is the primary advantage of a folding rule?
The primary advantage is its portability and extended measurement capability in a compact form. It can reach up to 1 meter and then fold down for easy storage.
What does 'Class III electrolytic indelible graduation' mean?
This refers to the standard of accuracy for the markings on the rule and the method used to make them permanent. Class III is a common standard for general-purpose measuring tools, and 'indelible' means the markings are resistant to fading or wearing off easily.
Is this rule suitable for professional construction?
Yes, it is suitable for many professional tasks, particularly where portability and measurements up to 1 meter are needed. For extremely high-precision architectural or engineering work, higher accuracy classes might be considered.
How do I maintain the brass springs?
The Dural brass springs require minimal maintenance. Ensure they are kept clean and dry. Avoid bending them excessively.
Can I use this rule for very fine detail work?
The millimeter graduations allow for precise measurements. However, the nature of a folding rule means it might have slight flex compared to a rigid ruler. For ultra-fine detail, ensure the rule is fully extended and stable.
What is the finish of the rule?
The rule has a natural aluminum finish.
Troubleshooting
Rule joints feel stiff
Gently clean the brass springs and folding mechanisms with a soft brush to remove any dust or debris. A very small amount of lubricant may be applied to the springs if necessary, but avoid excess that can attract dirt.
Graduations are difficult to read
Ensure the rule is adequately lit. The natural finish may require good lighting. Clean the surface of the rule to remove any smudges or dirt that could obscure the markings.
Rule does not lie flat when extended
Check that all folds are fully extended and locked into place. Ensure no debris is caught in the joints preventing a straight extension. Apply gentle, even pressure to straighten if minor warping has occurred due to storage.
