This is the most versatile and precise rule Incra offers. This Professional T-Rule is in a 12"/300mm length and features Incra's patented marking holes at every 1/16th, 32nd, 64th & 1/100th inch.
But they are also bilingual because they have marking holes at every 0.5mm as well! The end features 3 vertical inches of marking holes at every 32nd inch. You will never be without the correct measurement with this rule.
This is also available in a 6"/150mm version.
