- Magnetic design for secure side mounting on ferrous surfaces: a strong side magnet attaches to metal surfaces for hands-free operation and easier handling during setup. - Magnetic and user-friendly design: the side-mounted magnet securely holds to iron surfaces to optimize handling during installation. in addition, a high-resolution side digital scale enables simultaneous measuring and marking, while the lower carrying buckle prevents loss and facilitates transport. - Built for professional use: made from a robust combination of ABS plastic and aluminum alloy to withstand harsh environments while maintaining readability under all conditions. Ideal for professional tradespeople and hobbyists alike, delivering precise alignment and measurement for any task. - Three precise measurements: vertical, horizontal, and 45 degrees, with dual high-precision horizontal bubbles for increased accuracy. - Use scenarios: - On construction sites for mounting and aligning components to metal structures or studs. - Electricians mounting devices or fixtures to metal surfaces and marking drill points. - DIY projects in workshops or garages requiring quick, accurate layout on metal surfaces.
