Remember when marking your workpieces was a breeze? With the WEN Pocket Marking Edge Ruler, getting accurate measurements won’t be an issue again. The holes on the Edge Ruler are designed to simplify marking and layout, as well as to help drawing parallel lines for mortises and more. With a large edge that wraps around your workpieces for improved stability and accuracy, you’ll be able to mark your workpieces with a new sense of precision, drawing perfectly straight and parallel lines. The 1mm holes are spaced every 1/32 inch for precise lines and markings. The ruler is also highly durable thanks to its rust-resistant, CNC-machined anodized aluminum build, and fits easily in a pocket or the palm of your hand. Remember when inaccuracy was a thing of the past? Remember WEN.
