Detect centerlines instantly across a wide range of materials (0–58 mm thickness), so you get accurate layout for joinery and sawing tasks without repeated measuring or guesswork. Stable, warpresistant frame provides consistent, linear marking motion for repeatable tracing and clean lines; maintains precision performance even with frequent use. Hardanodized finish resists oxidation and abrasion to preserve a smooth glide and longterm calibration retention, reducing maintenance and downtime. Contoured antislip palm grip improves handling and evenly distributes weight to minimize hand fatigue during extended marking or layout sessions. Designed for compatibility with common woodworking operations—use it wherever reliable centerline detection and steady marking are required. Practical applications Dowel, mortiseandtenon, and tenon layout: mark exact centerlines on boards and rails up to 58 mm thick for accurate joinery fit and consistent results. Ripping and saw setup: quickly transfer center or reference lines to guide saw cuts and ensure repeatable, straight rip lines across multiple workpieces. Cabinet and furniture assembly: create precise, repeatable marking for multiple identical parts so assembly and alignment are faster and more accurate. Why this tool solves common problems Eliminates repeated measuring and alignment errors by providing instant centerline detection across a broad thickness range. Reduces inconsistent marks and wobble thanks to a warpresistant frame and stable linear motion, improving fit and finish. Lowers maintenance and preserves accuracy over time via a durable hardanodized surface, while the ergonomic grip reduces user fatigue during longer jobs.
