PRECISION MEASURING: The pocket ruler is wide and the slide square is securely attached to the rule, allowing for accurate measurements during drafting and woodworking tasks. The adjustable sliding mechanism locks tightly in place and enables easy surface measurements. Two thumb screws keep the slide secure and prevent loosening during use. THICK AND DURABLE: The straight-edge metal pocket ruler is made of high-quality aluminum alloy. The ruler is rigid, 1 inch wide, 5/32 inch thick, and features a red finish. Machining, lettering, and finish are precise and excellent for marking and scribing lines. CLEAR SCALE: The woodworking ruler is easy to read and functions smoothly. It is pocket-sized and features both inch and metric scales. The laser-etched markings are set in permanent grooves that will not fade over time. VERTICAL SCALE: The vertical scale ranges from 1/4 to 3/4 inch and can be used to measure the height of table router bits or table saw blades. A small hole is included to hold a pencil, keeping it in place while drawing alignment lines, making it effective for marking tasks.
