Incra BNDRUL06 6-Inch Incra Precision Bend Rule
The New INCRA Bend Rule is precisely what you need for layout and measurement along the edge of a board or other workpiece.  We've put micro-fine marking holes every 1/16", 1/32" and 1/64" to instantly locate your sharp pencil point or scribe EXACTLY on target with zero uncertainty, zero parallax and zero eye strain.  The 90 deg. shape holds it snugly in place while the two scale surfaces let you mark and measure on the top, edge and corners simultaneously.  There are even two vertical end scales with marking holes for drawing precision parallel lines relative to the edge of your work.  Available in 6", 12" and 18" lengths.  Engraved stainless steel.
