Magnetic attachment This digital protractor features a robust magnet that securely attaches to metal surfaces, enabling hands measurements and stable readings during your work. Dual measurement modes Offers both relative and absolute measurement options, providing flexibility for tasks that require reference angles or independent measurements. Angle and slope conversion Easily switch between angle readings and slope percentages to suit construction or carpentry projects that require different measurement formats. Data lock function A convenient data lock freezes the displayed measurements for easy reading while you work, reducing the need to view the display continuously. Key benefits Hands operation with secure attachment to metal surfaces for improved workflow and stability. Flexible measurements with dual modes to cover different tasks and reference needs. Quick and simple conversion between angle and slope readings to match project requirements. Readability and accuracy maintained by a data lock function that freezes the measurement display. Use scenarios Installing metal brackets or frames where precise alignment is critical and hands measurement saves time. Checking the pitch or slope of roofing, stairs, or shelving to ensure correct angles and levels. Verifying bevels and angles in woodworking or carpentry projects, such as setting miter cuts or aligning joints.
