The unit features a 175 lb magnetic pull force to hold position firmly on ferrous machine surfaces, and an articulated arm with fine adjustment capability for precise indicator positioning. The rectangular magnetic base measures 60 mm in length and 55 mm in height, providing a stable footprint on milling tables, surface plates, lathes, and similar metalworking equipment. At 1.7 pounds, the assembly is compact enough for bench-top and machine-tool use.\u003c\/p\u003e\n\u003cp\u003eThis positioner holder is suited for metrology and quality control applications in machine shops, toolrooms, and manufacturing environments. It is typically used when setting up dial indicators for runout checks, bore alignment, surface flatness verification, and part inspection routines. The magnetic base activates and releases quickly, allowing repositioning without disturbing the workpiece setup. The articulated arm gives technicians the reach and angle flexibility needed to position the indicator tip precisely on the feature being measured.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e175 lb magnetic pull force holds securely on ferrous surfaces during measurement\u003c\/li\u003e\n  \u003cli\u003eArticulated arm design allows flexible positioning around workpieces and fixtures\u003c\/li\u003e\n  \u003cli\u003eFine adjustment mechanism enables precise indicator tip placement\u003c\/li\u003e\n  \u003cli\u003eRectangular magnetic base included — no separate base purchase required\u003c\/li\u003e\n  \u003cli\u003eOverall arm reach of 435 mm provides extended positioning range\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 1.7 pounds for easy repositioning on the bench or machine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style magnetic base indicator holder compatible with standard dial indicators and test indicators used in general metrology and machine-tool inspection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a clean, flat ferrous surface for the magnetic base to achieve full rated pull force — remove chips, coolant, and debris from the mounting surface before activating the magnet. No tools are required to mount or reposition the base. The articulated arm joints should be snugged firmly before taking a measurement reading to prevent indicator drift. Power down or lock out rotating equipment before placing or adjusting the indicator holder near moving parts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic Pull Force\u003c\/strong\u003e: 175 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Style\u003c\/strong\u003e: Articulated Arm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFine Adjustment\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Arm Length\u003c\/strong\u003e: 435 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Mount Type\u003c\/strong\u003e: Magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 55 mm (2.17 inches)\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: 1.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: MS160412017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689740435762,"sku":"MS160412017","price":150.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/444c8e2315ca0aa24f1e01fdd36f5be4.jpg?v=1788263674","url":"https:\/\/voomisupply.com\/products\/spi-ms160412017-indicator-positioner-holder-175-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
