Ergonomic lightweight body reduces pressure on the elbows and wrists during measuring and marking, supporting comfortable use over extended tasks. In addition to length measurement, the calipers can measure depth and height, offering versatile functionality for multiple measurement needs. Simple, easy to use design enables quick setup and straightforward operation with minimal training. The scale is clearly visible, allowing fast and accurate readings to save time on projects. Use scenario: In woodworking, determine shelf depths or groove depths and verify piece heights before cutting or assembling. Use scenario: In metalworking, measure hole depths, overall part heights, or step heights to ensure components fit together precisely. Use scenario: For DIY and home improvement, perform quick dimension checks during furniture assembly, hardware mounting, or when evaluating clearances in tight spaces.
