INCRA Precision Marking Rule 300mm

Original price £29.95
Current price £23.96

INCRA's Precision Marking 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.

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 marking holes at every 1mm whilst the four centre rows of holes are at 0.25mm increments along its entire length
    • Draw a short line at any mm spacing using the outside slots or by selecting the centre rows and twisting your mechanical pencil you can spot mark any measurement to 0.25mm, 0.5mm, 0.75mm  or 1.0mm; this gives these rules the best accuracy you can achieve when marking out.

    Also available in 150mm, 6" and 12" versions plus 10"/250mm Dual Scale.

    Precision Marking Rules are also available in INCRA Rule Sets - 300mm.

    FREE UK Delivery on all orders over £30 within the UK Mainland, Northern Ireland, Highlands & Islands, for a limited time only*. Only £5.95 on orders under £30.

    quality rule that makes accurate marking a doddle.

    Love it. Pricey but outstanding quality as you would expect from the company. Easy to use and mark my work accurately.


    I am using this for model making and would recomend it for acuracy.

    Remarkable accuracy

    Have looked at these rules in the past and wondered what could make them worth the money, I now know. My eyesight although good isnt quite what it used to be and I have found it difficult making repeated small measurements with a normal ruler. The Incra make this a thing of the past I now find it extremely easy to make tiny measurements and more importantly make them repeatedly. Yes I would reccomend these products for their great accuracy.

    Incra quality is not a luxary.

    Like most amateurs, I always have to justify what I purchase. However, the quality Incra products and resulting accuracy immediately justifies the cost which will become less the more I use this beautifully engineered tool.


    Simply brilliant
