Fast positioning - Facilitates rapid setup for a range of arc sizes used in edge and inlay projects. Delivers reliable accuracy and consistent performance with minimal adjustments. Thoughtful design - Uses symmetric arc calibration to optimize manual measurements. Addresses R-angle and C-angle requirements and reduces processing time for greater task efficiency. Effortless use - Reduces work by avoiding complex tools. Minimizes time and physical effort for positioning and is intuitive to apply in router edge radius projects. Durable construction - Wear-resistant and impact-resistant materials maintain long-term accuracy during precision work. A smooth exterior supports reliable performance. Use scenarios - Edge radius tasks on furniture, cabinetry, and decorative edges where multiple radii are required and quick setup improves workflow. - Inlay and pattern work on wooden panels that require symmetric arcs and consistent measurements across pieces. - Sign making or decorative routing that uses curved features and precise arc radii, benefiting from fast alignment and repeatable results.
