?Upgrade Framing Ruler?Made of high quality aluminum alloy with anodized surface and laser engraved scales. We investigated the pain points of L-shaped rulers on the market and completely upgraded the product. Aluminum alloy material: prevent the ruler from rusting, lighter and smoother to use. Anodizing process: has stronger adhesion than electrostatic spraying process, more wear-resistant and durable. Laser scale: will not fall off, the scale is clearer, more readable. ?Innovative Scale Positioning Design?Serrated scale positioning groove on the L-shaped ruler, this is our new innovation of this product, so that you can mark and position more accurately, especially when you use it as a carpentry framing square, with the stair gauge, you can easily draw a straight line or parallel lines corresponding to the scale. ?Multifunctional L Ruler?This L-shaped ruler can be used as a straightedge to measure lengths and scribe lines, for drawing right angles or determining right angles. Combined with the stair gauge to give you an accurate layout of your framing jigs, you don't need to re-align the framing squares each time to mark the next step. Ensure that every staircase is perfectly consistent. A great companion for your design, carpentry, tailoring, and everyday DIY! ?Vibrant Colors? Compared to electroplating and electrostatic spraying, anodizing process brings a higher quality feel and look. Vibrant colors make it easier to find it in a pile of tools. ?Accurate and Esy to Read Scale?Silver-colored scales engraved on a red background make the scale easy to read. The laser-engraved scales do not need to worry about peeling off or wear and tear, and can adapt to harsh environments, greatly enhancing the tool's lifespan.
