Woodworkers, carpenters, DIYers—this adjustable scriber and T-square ruler is about to become your new best friend. It's a 15.9-inch (405mm) aluminum alloy ruler with a sliding head that you can set to any angle you need. The main ruler has clear laser-engraved scales in both inches and metric, so you can measure and mark with precision. The cool part? You can loosen the big ABS knob, slide the head up and down to adjust the length, or rotate it to set an exact angle (thanks to the angle scale on the head). Then tighten it down, and it locks securely—no slipping while you're scribing a line. The whole thing is lightweight but super sturdy, with a 5mm thick ruler body and a 6mm thick head. It's perfect for marking parallel lines, finding angles, transferring measurements, or just as a reliable straightedge. Great for woodworking projects, metalworking, drafting, tiling, you name it. If you're tired of fiddling with multiple tools or guessing angles, this all-in-one scriber saves you time and hassle. Get those cuts and joints perfect every time.
