It expands from 3\/8 inch to 1\/2 inch, allowing machinists to set consistent, repeatable gaps when indicating bores, setting up vises, or supporting workpieces during milling and grinding operations. At 1-3\/4 inches in length and 9\/32 inch thick, this parallel fits into tight spaces where fixed parallels cannot. The unit weighs approximately 1 pound. Machinists, tool and die makers, and CNC setup techs rely on adjustable parallels like this one when fixed-size parallels do not match the required height or gap dimension.\u003c\/p\u003e\n\u003cp\u003eThe SPI 14-872-6 is suited for use in machine shops, toolrooms, and maintenance environments where precision workholding and setup accuracy are required. It is appropriate for use with milling machine vises, surface grinders, and inspection setups. The adjustable range of 3\/8 to 1\/2 inch makes it useful for a variety of workpiece heights and fixture configurations without requiring a full set of fixed parallels for every application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable range from 3\/8 inch to 1\/2 inch for flexible setup work\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1-3\/4 inches fits compact vise and fixture applications\u003c\/li\u003e\n  \u003cli\u003eThickness of 9\/32 inch (0.2813 inch decimal) provides a low-profile fit in tight clearances\u003c\/li\u003e\n  \u003cli\u003eDesigned for repeatable parallel support during milling, grinding, and inspection\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for toolroom and production machine shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose adjustable parallel for use in standard milling vises, surface grinder setups, and precision workholding fixtures where a 3\/8 to 1\/2 inch height range is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAdjustable parallels are installed and adjusted by machinists or toolroom technicians — no power lockout is required, but all machine motion should be stopped and the vise or fixture should be clear before placing or adjusting parallels. Ensure the parallel is fully seated and locked at the desired dimension before clamping the workpiece. Do not use adjustable parallels as cutting tool supports or in applications that exceed their rated size range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 1\/2 inch (0.5 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 9\/32 inch (0.2813 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 14-872-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689297183026,"sku":"14-872-6","price":25.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/898e235d57d103906467aeee06b6a33d.jpg?v=1788257054","url":"https:\/\/voomisupply.com\/products\/spi-14-872-6-adjustable-parallel-3-8-to-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
