Key benefit: easy, reliable holding for precision measurement and alignment On/off magnetic base allows smooth switching with minimal force, reducing wear on the indicator and the working switch and protecting them from damage. Permanent alloy magnet provides consistent holding power for repeatable setups and stable readings. Central locking mechanism prevents accidental release; integrated springs add extra stabilization and safety during use. Durable, corrosion-resistant construction Made from high-grade alloy steel with a protective shell to ensure long-lasting durability and maintain a clean appearance in workshop environments. Rust-resistant materials reduce maintenance and extend service life. Versatile and quick to set up Adjustable design lets you position and secure the task or instrument at virtually any angle for flexible measurement and alignment. Fast repositioning and locking save setup time and improve workflow for repetitive tasks. Function, compatibility, and performance Designed to work with dial indicators and similar measuring instruments that require a stable magnetic base and precise positioning. Combines a permanent magnet with a dependable locking system and spring stabilization to deliver steady, accurate support during mechanical correction and technical measurement. Typical applications Machining and metalworking: hold dial indicators or test probes for runout, flatness, and concentricity checks. Equipment alignment and assembly: secure measuring instruments while aligning shafts, housings, or fixtures. Quality control and inspection: provide a stable reference for precision measurement tasks on the shop floor or in the inspection lab. Why choose this magnetic base Protects sensitive indicators and switches by minimizing switching force. Built to resist corrosion and mechanical wear. Stable, lockable hold with spring-assisted safety for confident, repeatable measurements.
