It features an articulated arm mounted to a rectangular magnetic base with a 175-pound magnetic pull force, providing a secure, vibration-resistant hold on ferrous machine surfaces. Fine adjustment capability allows technicians to position dial indicators, test indicators, and similar instruments with high positional accuracy. The base stands approximately 2.17 inches tall and extends 60 mm in length, and the overall arm assembly reaches 365 mm in total length. The unit ships complete with the magnetic base included. This tool is installed by machinists, metrologists, and quality control technicians performing runout checks, surface comparisons, or setup verification.\u003c\/p\u003e\u003cp\u003eThis indicator holder is suited for use in precision machining, grinding, and inspection setups where a stable, repositionable instrument mount is required. The articulated arm design allows the indicator to be positioned at virtually any angle relative to the workpiece or machine table. It is appropriate for both manual machining centers and inspection benches equipped with ferrous steel surfaces. The magnetic on\/off base allows the user to reposition the holder quickly without disturbing adjacent fixturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e175-pound magnetic pull force holds securely to ferrous machine surfaces\u003c\/li\u003e\n\u003cli\u003eArticulated arm allows multi-axis positioning of the attached indicator\u003c\/li\u003e\n\u003cli\u003eFine adjustment mechanism enables precise final positioning without backlash\u003c\/li\u003e\n\u003cli\u003eRectangular magnetic base with 60 mm base length and 55 mm base height\u003c\/li\u003e\n\u003cli\u003e365 mm overall arm length provides extended reach for deep-set measurement points\u003c\/li\u003e\n\u003cli\u003eIncludes magnetic base with arm — no additional mounting hardware required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose magnetic indicator holder compatible with standard dial indicators and test indicators that mount via conventional dovetail or post-style clamp connections typically found on this class of positioner arm.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or metrology technicians on clean, flat ferrous steel surfaces such as machine tables, surface plates with a steel base, or machine castings. Ensure the mounting surface is free of chips, coolant, and debris before activating the magnetic base to achieve full rated pull force. De-energize the magnetic base before repositioning the arm to avoid uncontrolled movement of the indicator. The unit does not require tools for setup but should be inspected periodically for arm joint wear that could reduce positional stability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Pull Force\u003c\/strong\u003e: 175 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArm Style\u003c\/strong\u003e: Articulated Arm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Mount Type\u003c\/strong\u003e: Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 2.17 inches (55 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Arm Length\u003c\/strong\u003e: 365 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFine Adjustment\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Magnetic Base with Arm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS160412016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715395846450,"sku":"MS160412016","price":115.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc91c6c27f01df631151158802a69aab.jpg?v=1788513299","url":"https:\/\/voomisupply.com\/products\/spi-ms160412016-indicator-positioner-holder-175-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
