• The Width is widened so that Levels etc can be placed on it for use.
• As a standard straight Edge it is suitable for measurement of Parallelism and straightness
• Use as standard or for inspection of machine running condition, Precision machinery assembly, fixing of turbines for generating plants, etc.
• Straightness and Parallellism (Not same as JIS height) clears the requirements for Straight Edge JIS Standard (JISB7514)
• There are hardened and non hardened types.

*According to the requirement, we can also manufacture special Grade products
*The box enclosure is a robust type used also for transportation

NOTE

Bezel Point

*Straightness Measurement

For our products, the minimun deflection point (bessel point) is specied by the Straight Edge, and Straightness Measurement is performed. The distance from both edges to the support position P :

P=0.2203×L　(L=Lenght Lenght mm)
