- Carpenter's Square Ruler for Woodworkers: A steel ruler that wraps around the panel edge, giving a readable dual‑sided scale. Laser‑etched marks stay legible, delivering durability, precision, and simple operation. - Ultimate Layout Tool for Angled Panel Projects: Head adjusts from 0° to 70°, with locking screws every 5° (including 22.5° and 67.5°). Press the head to the desired angle, then press the straight edge for accurate lengths and reference angles. - Secure Screw Design: Movable head screws lock securely. Press the straight line to obtain an exact angle on the 10-inch (25.4 cm) ruler for reliable panel layouts. - TSquare Design: Precision indexing with a series of machined holes and a spring‑loaded, tight‑tolerance indexing pin that snaps into place and locks for consistent accuracy. Use scenarios - Create cabinet frames or router‑edged panels with repeatable miter and angled joints. - Layout shelves, back panels, or inserts that require non‑90° angles with precise references. - Transfer and replicate exact angles for frames, dado layouts, or angled bracing in projects.
