Edge Ruler for Woodworkers — 25.4 cm steel T‑square with adjustable angle head Why you need this tool Makes marking and laying out angled cuts on large panels fast and accurate. The ruler wraps around the panel edge so you can transfer measurements and angles without guessing or extending a small protractor. Reduces cumulative layout errors on sheet goods. A small mistake extended across a large panel becomes a large error; this tool holds a fixed reference for repeatable, point‑accurate lines. Built from steel with laser‑etched graduations for long‑lasting legibility and reliable performance on jobsite or in the shop. Key features Edge‑wrap design: the ruler clamps to the panel edge and provides a clear scale on both faces for left‑ or right‑hand marking. Adjustable angle head: head locks between 0° and 70°; detents every 5° plus indexed positions at 22-1/2° and 67-1/2° for common cuts. Secure locking screw: fixed screw design lets you move and firmly lock the head so the angle stays set while you scribe. T‑square indexing system: a series of precision machined locating holes and a spring‑loaded, tight‑tolerance indexing pin that snaps into place for repeatable, point‑accurate alignment. Durable construction: steel ruler and angle mechanism with precise laser etching — easy to read, wear resistant, and built for heavy use. Size: 25.4 cm (10 in) ruler length — compact enough for control, long enough for clean layout lines on typical panels. How it works (simple steps) 1. Wrap the ruler around the panel edge so the body sits squarely on the face. 2. Set the head to the desired angle (0°–70°) and tighten the screw; use the indexed detents for 5° increments or the 22-1/2°/67-1/2° positions. 3. Use the laser‑etched scale and the T‑square indexing pin to scribe a straight, accurate reference line across the panel. Practical applications Cabinet and furniture layout: mark consistent angled reveals, rails, stiles, and panel joins on plywood, MDF, and solid wood panels. Sheet goods cutting and shopprep: transfer precise cut lines directly from the panel edge for circular saw or track saw cuts, keeping the saw path accurate over long runs. Trim and mitre work: lay out repetitive angled cuts for door trims, window casings, and stair parts where repeatability matters. Compatibility and performance Compatible with common sheet materials (plywood, MDF, particleboard, laminated panels) and typical panel thicknesses — designed to wrap and reference from the edge. Performance geared toward repeatable, workshop‑grade accuracy: steel construction, secure locking, and indexing pin minimize play and cumulative error. What you get A 25.4 cm steel edge ruler with adjustable angle head, locking screw, precision indexing holes, and spring‑loaded indexing pin. Laser‑etched scales on both sides for clear, durable markings. Simple, reliable, and built for panel layout — this edge ruler gives you a fixed, repeatable reference for accurate angle and length marking on large panel projects.
