Application and selection

Place the knife-edge straightedge on the surface or edge under test. A visible light gap quickly reveals deviations in straightness or flatness.

Technical design

The measuring edge is hardened and finely lapped. A hand heat guard reduces direct thermal influence. The design follows DIN 874.

Variants and use

Choose blued carbon-steel versions with non-glare inclined faces or matt stainless-steel versions. Both ranges cover 75 to 1000 mm.

Advice and service

Ballbach assists with material and length selection and with proper storage and protection of the sensitive edge.
