Extended Reliability: Thermal compression manufacturing technology provides impact resistance while preserving straight angles for decades of regular use. Fatigue precision: Slim profile with rounded edges enables stable finger positioning. Readable graduated scale supports repeated measurements without excessive hand stress. Streamlined efficiency: Compact design with dual centimeter and millimeter scales and a nonslip surface for quick, stable onehanded measurements. Ideal for tight workspaces or heightlimited interventions. Universal use: Allinone tool for floor coverings, detecting vertical defects, fitting tile joints and repairing wall plasters across a range of professional settings. Use scenario: Tile and floor installation projects. Verify joint widths, confirm straight edges, and check tile thickness across surfaces to ensure consistent alignment. Use scenario: Wall plaster and vertical alignment work. Detect vertical defects and verify plaster thickness or joint alignment during repairs or renovations. Use scenario: Confined or overhead applications. Onehanded measurements during cabinet installations, baseboard fitting, or other heightrestricted tasks where space is limited.
