INCRA - Rule - Precision Straight 10in/250mm Dual Scale

Regular price £25.95


IINCRA - Rule - Precision Straight 10in/250mm Dual Scale 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.

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.

Imperial/Metric Precision Rule (Straight) - 10"/250mm (Dual Scale)

  • INCRA'S Micro-fine patented guide holes and slots at every 1/20 of an inch.
  • INCRA'S Micro-fine patented marking holes at every 1mm. 
  • Instantly locate your sharp pencil or scribe at the exact measurement with zero uncertainty and no eye strain!

Incorrect specifications

I was disappointed that this 10” Incra rule didn’t come as specified, if there was a higher resolution photo to suit this rule, I would have gone for one of the other rules on sale. The millimetre scale is 1mm only, not 0.25mm, 0.5mm, 0.75mm, and the Inch scale is only 1”, 1/10" & 1/20” not 1/16”, 1/32” & 1/64” as specified.
For my purposes 1/10 and 1/20” resolution is next to useless, which is a shame because the rule is very accurate and easy to use.

Please accept my apologies and thank you for bringing this error to our attention. We have updated the product description and refunded your payment in full. Please keep the Incra rule which I hope you find useful although not what you originally requested. Thank you for your custom and patience.
Brilliant . Best ruler i have ever used

I have a bookfolding business requiring accurate measuring. I have tried many ways to mark my books but was never 100% satisfied until now. This is the most precise ruler i could have hoped for and my work now feels accurate.

Precisely perfect

Precisely perfect for my exacting needs.
