450mm Veritas Edge Rule

The great advantage of this style of rule is that it saddles the edge of a workpiece, making it easy to hold accurately in position when measuring and marking layout lines.
Ours have an acute interior angle to ensure that they seat well, even over saw whiskers, and bevelled edges with etched graduations to minimize parallax errors. This design also simplifies transfer of perpendicular lines from face to edge, and is particularly convenient when holding and marking off dowel rod stock. 
The wide leg on the L-shaped cross-section is for face work, while the shorter leg is for narrow stock and edge work.
Available in 150mm, 300mm and 450mm lengths. The smaller rules have faces with depths of 3/4" and 3/8"; the 450mm rule has face depths of 1" and 7/16". 
You can also use the rules on a flat surface – and, since the shape makes them much easier to pick up than a flat rule, you may find yourself reaching for them as your go-to rules. The 150mm rule is small enough to fit comfortably in a pocket.
Made in Canada from aluminum with a black anodized finish.
