The base uses a powerful 160-pound magnetic pull to grip ferrous surfaces, keeping the indicator stable while measurements are taken. A built-in on\/off switch lets the technician engage or release the magnetic field quickly without disturbing the setup. The lug-style mount is compatible with standard indicator stems and accessories. This type of base is a standard tool in machine shops, fabrication environments, and precision metrology setups where consistent, vibration-free indicator positioning is required.\u003c\/p\u003e\n\u003cp\u003eThe 14-402-2 is suited for use on milling machines, surface plates, engine lathes, grinders, and similar ferrous machine tool surfaces. It is commonly used by machinists, tool and die makers, and quality control technicians to position dial indicators, test indicators, and comparators for runout checks, surface flatness verification, and part alignment. The compact footprint makes it practical in tight setups where larger bases would obstruct access.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e160-pound magnetic pull for firm, stable attachment to ferrous surfaces\u003c\/li\u003e\n  \u003cli\u003eOn\/off switch allows quick magnetic engagement and release without shifting the setup\u003c\/li\u003e\n  \u003cli\u003eLug-style mount accommodates standard indicator stems and accessories\u003c\/li\u003e\n  \u003cli\u003eCompact base footprint at 2.25 inches long, 2 inches wide, and 2.125 inches tall\u003c\/li\u003e\n  \u003cli\u003eLightweight at 2 pounds for easy repositioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard lug-mount magnetic indicator base for use with dial indicators, test indicators, and comparators on ferrous machine tool surfaces and surface plates.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlace the base on a clean, flat ferrous surface free of chips, oil, and debris to achieve full magnetic holding force. Engage the on\/off switch only after positioning the base to avoid uncontrolled attraction to the work surface. Verify the indicator stem is fully seated and locked in the lug before taking measurements. No permanent mounting or wiring is required for this product.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic Pull\u003c\/strong\u003e: 160 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e: On\/Off Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: 14-402-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690876502322,"sku":"14-402-2","price":30.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8874e04f4a0feaa8254a43836ab02ee2.jpg?v=1788276774","url":"https:\/\/voomisupply.com\/products\/spi-14-402-2-magnetic-indicator-base-on-off-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
