GTI Aluminum 20” Radius Sanding Block for Fretboard – 17.7″ x 2.76″ – ALU450-20

Description

• PRECISION 20-INCH RADIUS: Accurately manufactured to create and maintain a consistent 20-inch radius on guitar and bass fingerboards. Its long, uniform sanding surface helps produce an even and repeatable contour across the entire fingerboard.
• PROFESSIONAL FRET LEVELING: The 450 mm length provides a stable and continuous sanding surface for accurate fret leveling. Its extended size helps distribute pressure evenly and reduces the possibility of creating isolated low or high spots.
• DIMENSIONALLY STABLE ALUMINUM: Manufactured from durable aluminum for excellent straightness, accuracy and long-term stability. Unlike wooden sanding blocks, it is unaffected by normal changes in moisture or temperature and will not swell, shrink or warp under typical workshop conditions.
• COMFORTABLE ERGONOMIC PROFILE: The 70 mm width and 30 mm thickness provide a comfortable and secure grip for controlled sanding. Its lightweight hollow profile makes the tool easier to maneuver while maintaining the rigidity required for precision fretwork.
• VERSATILE LUTHIER TOOL: Suitable for building or correcting a 20-inch radius on guitar and bass fingerboards, leveling installed frets and preparing surfaces during instrument construction or repair. It can also serve as a dependable clamping caul during fret installation.
• DURABLE PROFESSIONAL CONSTRUCTION: Designed for repeated use by professional luthiers, guitar builders, repair technicians and musicians who maintain their own instruments. Made with a durable silver aluminum finish and a total weight of approximately 31 oz. This sanding block is formed using a precision aluminum extrusion die rather than CNC machining, so slight variations within normal manufacturing tolerances may occur without affecting its intended performance.
