Precise visible scale: Clear, easy-to-read scale on the linear arc scribing tool lets you set and repeat measurements quickly so lines and arcs stay accurate across multiple workpieces. Draw parallel lines and transfer shapes: Use the tool to scribe parallel lines, copy curves, and trace patterns directly onto wood. Adjustable geometry lets you create a wide range of arcs and offsets without guesswork. Fully adjustable and lockable: The tool changes shape to suit the task. Adjust the pen holder tension and the arm positions to produce different radii and offsets, then lock the device at any setting for consistent, repeatable results. Compact, lightweight, easy to carry: Small footprint and light weight fit comfortably in a pocket. Built-in shirt/pants belt clip makes it convenient to carry on the jobsite or in a workshop. Durable construction: Manufactured from high-quality material for reliable performance and long service life under normal woodworking use. Use scenarios Cabinetry and trim: Quickly scribe parallel lines and match trim profiles or offsets when fitting moldings and fascias. Pattern transfer and layout: Copy template curves or transfer complex shapes from one workpiece to another with consistent accuracy. On-site marking: Lightweight and pocketable for fast layout and marking when working in tight jobsite conditions. Compatibility note Make sure this fits: enter your model number.
