Incra T-Rule 150 mm

Metric T-rule from Incra, 150 mm, for accurate layout of measurements and lines. The T-bar registers against the edge of the work, so you can draw lines square to the edge and lines parallel to it. The T-bar is easy to adjust.
The rule has Incra's patented marking holes at every full, 1/4, 1/2 and 3/4 mm from 0 to 150 mm. On the end are height marking slots from 0 to 50 mm, for example for setting bit or blade height. You mark with a 0.5 mm mechanical pencil.
The rule is about as thin as a business card, which reduces parallax error compared with thicker rules, and flexible enough to follow surfaces that are not perfectly flat.
Also available in 300 mm.
