Swan Tool Group Red Tail Offset Ruler

The black locking slider on this 8'' anodized aluminum ruler expands its utility for drawing angles. Use the tool with the ruler-side down for general measuring, marking and layout tasks. Or flip the tool over so the slider faces down instead. Now you can position the slider against the edge of your workpiece to mark perpendicular or 45° layout lines facing left or right. The slider can be set and locked anywhere along the length of the ruler for greater convenience.

The ruler also provides Swan Tool Group's Tru-Mark Precision Marking Technology: both long edges on one side have a tiny rabbet that offsets the tip of your pencil when drawing a line. It lets you hold the ruler's edge precisely where the line needs to be drawn without having to shift it slightly off the mark to account for the lead's thickness. That minimizes the chance for parallax errors when measuring and marking parts. In the same way, a pencil saddle indentation on one end positions the tip of your pencil lead exactly at the ruler's edge for accurate line placement.
