Precise positioning for varying arc sizes Designed for different arc sizes, it enables quick alignment at cabinet edges and during routing tasks, improving precision and repeatability with minimal effort. Practical design for accuracy and speed Symmetric arc calibration covers both R-angle and C-angle to ensure accurate results and shorten setup time, supporting an efficient workflow. User friendly and intuitive No complex tools required; the physical positioning is intuitive and easy to use for smooth handling of router corner radius templates. Robust and stable construction Wear-resistant and impact-resistant design provides consistent precision over time through advanced machining, with no rough edges or burrs. Use scenarios - Edge work on cabinets and furniture: routing rounded corners on fronts, doors, and decorative panels. - Reproducing identical radii: produce multiple pieces with the same corner radius for production runs. - Template-based routing: fast setup for precise rounded corners when shaping boards and panels.
