Use these highly accurate straightedges as a guide to scribe and cut straight lines and to check surface straightness. Accuracy is the straightness tolerance over the entire length of the straightedge.
Aluminum is lightweight.
Stainless steel is corrosion resistant.

Straightedges with Graduations
Inch
Metric
Highly accurate, these straightedges work as a guide to scribe and cut straight lines and to check surface straightness. They have graduations, so you can take measurements as you go. Accuracy is the straightness tolerance over the entire length of the straightedge.
