Versatile Thickness Support: Detect centerlines instantly while ensuring compatibility with joinery and sawing projects, offering precision across materials with a 058mm thickness range for accurate outcomes. Stable Marking Motion: Designed for consistent tracing performance, the warpresistant frame supports stable linear marking motion while maintaining precision standards for accurate woodworking tasks. Strong Material: Smooth glide makes for effortless usage while resisting abrasion and maintaining longterm calibration retention with an oxidationproof hardanodized coating for consistent performance. Reduced Hand Fatigue: Combining ergonomic handling with balanced weight distribution, the contoured design reduces strain and enhances control for effortless use. Use scenarios: Cabinet making and joinery: mark centerlines on boards up to 058mm thick to locate dowels, hinges, or mortises. Sawing and routing: trace centerlines along long stock to guide repeatable cuts such as dados or mortises. Furniture fabrication and hobby projects: quickly identify centerlines on thick components to ensure symmetry and proper alignment.
