Draw precise angles fast: Built-in guides let you mark 45°, 90° and 135° angles in multiple directions, making layout for miters, corners and joint fits simple and repeatable. Dual-scale measuring: Clear, easy-to-read Mara-König markings include both inch and metric scales plus 1/2 and 3/4 depth units. Use the same tool for imperial and metric layouts without guesswork. Durable, lightweight construction: Made from anodized aluminum alloy for wear resistance and rust protection. The thickened construction improves stiffness for reliable, long-lasting measurements while remaining easy to handle. Stable vertical measurements: The ruler integrates with a T-track system (Stan D.) so you can insert it into cut edges, lock the stop and hold the tool vertical and steady for accurate plumb and depth checks. Key attributes Functions: angle marking (45/90/135°), imperial and metric measurement, depth units, T-track compatibility for vertical stops Material: anodized aluminum alloy (wear- and rust-resistant) Performance: stiff, precise, easy to read markings Compatibility: fits common T-track setups when used with Stan D. stop integration Practical use scenarios 1) Miter and trim work: Quickly mark 45° or 135° lines for miter cuts and check 90° squareness on frames, trim and moldings. 2) Layout and cutting: Use the dual scales and depth units to transfer measurements for crosscuts, rip cuts and joinery without switching tools. 3) Vertical and plumb checks: Insert the ruler in a T-track or edge cut, engage the stop (Stan D.) and hold the tool vertical for accurate plumb lines, drill guides or shelf layout. Why you need it Saves time by combining angle marking and dual-scale measuring in one tool. Improves accuracy with rigid, wear-resistant construction and clear Mara-König markings. Works with T-track setups for stable vertical measurements, reducing error on repetitive tasks. What to expect in use Clear inch and metric readouts with 1/2 and 3/4 depth units for versatile measuring. A lightweight, durable ruler that resists wear and corrosion while providing reliable stiffness. Straightforward T-track integration using Stan D. to keep the ruler vertical and locked for precise stops and repeatable layouts.
