|Pro T Rule 300mm by Incra
The Professional version of our patented T-Rules is shown here in the 6 inch/150mm version, these Professional T-Rules are also available in 12 inch/300mm lengths and both lengths offer 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 .5mm as well! The end features 3 vertical inches of marking holes at every 32nd".
These rules make short work of translating plans and drawings from US magazines.
