Stop guessing where your pencil point lands. The Ultra Precision Marking Ruler solves the biggest problem with conventional rulers — parallax error.

Instead of marking at the side of the ruler where your viewing angle causes inaccuracy, this ruler features micro-fine holes and slits that let you insert a mechanical pencil directly onto the exact measurement point.

With a scale as fine as 0.25mm and two-scale surfaces for marking on tops, edges, and corners simultaneously, it delivers dead-on accuracy every time. Available in 180mm, 200mm, 300mm, and 400mm.
