INCRA T-Rule 6"


INCRA's T-Rule offers unparalleled accuracy, having patented marking holes to mark in rather than just etched graduations, these Rules allow you to mark out precisely with no risk of error.  It's very easy to draw exact lines in either direction.

Just select the slot or hole, insert a 0.5mm mechanical pencil, and mark the measurement with complete accuracy - unmatched in the industry of Marking Rules!

One of the fundamental errors woodworkers make when measuring out is marking a line then marking the next measurement line from the first; compound errors soon build up - these Rules leave those kind of mistakes as a thing of the past.


  • INCRA'S Micro-fine patented guide holes and slots at every 1/16", 1/32", and 1/64", from 0 to 6 inches or 12 inches - it also offer 0 to 3" height markings on the end in 32nds.
  • Instantly locate your sharp pencil or scribe at the exact measurement with zero uncertainty and no eye strain! Our Professional T-Rules even offer marking holes every 1/100". This is unmatched in the industry.
  • The end reference bar can be easily removed or slid to to the left or right hand side of the rule allowing marking out tight into a corner of a cabinet or joint. It is also great for marking precise lines parallel up to 6" from an edge.
  • The T-Rule has an anodised aluminium fence keeping the ruler straight when marking out long lines.

    Available in 150mm, 300mm, 6" and 12" lengths.

      INCRA T-Rule 6"

      Excellent product when accuracy matters.

      Incra Rule

      Great Item and arrived quickly, only 1 disappointment it doesn't come with the pencil shown on the packing, so without it you need to already own a .5mm pencil or you can't use it properly.


      This a quality item, a little thinner than I thought it would be but still very good value, seems very accurate and well made. I brought this on a bit of whim to be honest but I have used a few times already and I very impressed with it. Nice touch to get the pencil as well FOC. Good communication and delivery time. This is the first time i have purchased from Wood Workers Workshop I will use them again I am sure.
