Secure, easy operation: built-in on/off switch on the base lets you lock the magnet quickly for secure holding of dial displays or test indicators during alignment and measurement tasks. Fewer slips and faster setups mean more reliable readings. Switchable permanent magnet: premium magnetic base provides firm, repeatable mounting on ferrous metal surfaces. The switchable design gives positive on/off control without adhesives or clamps, improving measurement consistency. Three-joint adjustable holder: the red adjustable magnetic base features a three-joint design for flexible positioning and high stability. Adjust the arm to the exact angle and lock it in place to keep indicators steady while you measure. Compatibility and function: designed for use with dial counting systems, dial indicators, and lever dial indicators. Works with standard test indicators and dial displays for a wide range of inspection and alignment jobs. Why you need it: prevents indicator movement and vibration that cause measurement errors, simplifies setup for repeat checks, and adapts to different workpiece geometries so you get accurate, repeatable results every time. Typical applications Machine alignment and spindle runout checks: hold a dial or test indicator steady while rotating or indexing shafts and spindles. Setup and fixture verification: secure an indicator during CNC or manual machine setup to establish accurate zero points or check part dimensions. Inspection and layout work: measure flatness, parallelism, or small deviations on workpieces and jigs where a stable indicator mounting is required.
