It uses a switchable permanent magnet to secure the base to ferrous surfaces such as machine tables, surface plates, and workholding fixtures. The base produces a magnetic pull force of 300 N, providing stable, vibration-resistant holding during measurement tasks. The articulating post and arm assembly extends to accommodate a wide range of positioning requirements. This tool is used by machinists, quality control technicians, and tool-and-die professionals in machine shops and manufacturing environments.\u003c\/p\u003e\u003cp\u003eThe SPI 20-208-5 is suited for use on manual mills, lathes, surface grinders, and inspection tables where a rigid, repositionable indicator mount is required. The post height of approximately 16.14 inches and the arm length of approximately 14.17 inches allow the indicator to be positioned over workpieces of varying heights and geometries. It is appropriate for both shop-floor and metrology-room applications where repeatable indicator placement is critical to dimensional verification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e300 N magnetic pull force for secure attachment to ferrous machine surfaces\u003c\/li\u003e\n\u003cli\u003eSwitchable permanent magnet base — no power source required\u003c\/li\u003e\n\u003cli\u003ePost height of approximately 16.14 inches and rod length of approximately 14.17 inches for extended reach\u003c\/li\u003e\n\u003cli\u003eBase footprint of 1.97 x 1.57 inches for compact placement on crowded setups\u003c\/li\u003e\n\u003cli\u003eCompatible with standard dial indicators and test indicators via articulating arm and post assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use magnetic base for precision dial indicators and test indicators mounted on ferrous surfaces in machine shop and inspection environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePower down or stop any rotating machinery before attaching or repositioning the magnetic base on a machine tool surface. Ensure the mounting surface is clean and free of chips or coolant film to achieve full magnetic contact and rated holding force. Tighten all arm and post locking knobs securely before taking measurements to prevent indicator drift. This tool does not require installation by a licensed trade but should be handled by personnel familiar with precision measurement practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Pull Force\u003c\/strong\u003e: 300 N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost Height\u003c\/strong\u003e: 16.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Length\u003c\/strong\u003e: 14.17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 20-208-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51701639840050,"sku":"20-208-5","price":101.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e816841dd9aedef8c3a3e6027b60fb8.jpg?v=1788402990","url":"https:\/\/voomisupply.com\/products\/spi-20-208-5-magnetic-indicator-base-300-n-pull","provider":"Voomi Supply","version":"1.0","type":"link"}
