Vial configuration - 1 horizontal vial and 2 vertical vials provide reliable level and plumb checks from a single tool, supporting simultaneous multi axis alignment. Accuracy and performance - Normal position accuracy: 0.5 mm per meter. - Overhead position accuracy: 0.75 mm per meter. - Designed to deliver consistent readings in both standard and overhead work, helping reduce misalignment on a variety of tasks. End cap design and usability - Removable end caps allow flush fitting in tight spaces or when integrating with other tools or surfaces. - Anti slip end caps give added grip for secure one handed marking and improved control during operation. Key benefits - Clear, multi axis orientation reduces guesswork when leveling or plumb ing corners, cabinets, shelves, and fixtures. - High accuracy in typical setups supports precise installations without rework. - Flush fitting capability enables neat, integrated marking in tight or joined installations. - Anti slip grip promotes steady, one handed operation for quicker work and fewer marking errors. Use scenarios - Hanging wall installations such as pictures, mirrors, cabinets, or lightweight shelves where both level and plumb must be verified at once. - Kitchen or bathroom counter and tile work where overhead marking and alignment are required for straight lines and plumb orientations. - General carpentry and woodworking projects that involve overhead work or tight joints, where reliable marking with one hand is advantageous. Notes - Maintains core specifications and functions as described: one horizontal vial, two vertical vials, accuracy figures for normal and overhead positions, removable end caps for flush fitting, and anti slip end caps for easier one handed marking.
