Knife straight ruler for testing the flatness of surfaces using the light gap method.
Note on the 500 mm aluminum-magnesium knife straight ruler!
The swivel range is ± 5° to the plane of symmetry because the hairline edge (test edge/test surface) is reinforced and more robust.
For a larger swivel range to the axis of symmetry, we recommend the TOP VERSION,
the hairline ruler with item no. 500.500TOP and a particularly slim test edge!
