Each parallel in the set adjusts across a range of 3\/8 to 2-1\/4 inches, making it adaptable to a wide variety of workpiece heights and configurations. At 5-1\/16 inches long and 9\/32 inch thick, these parallels are sized for use in standard milling vises and grinding setups. The set weighs approximately 1 pound. Machinists, tool-and-die makers, and skilled trade workers handling precision setups are the primary users of this tooling.\u003c\/p\u003e\n\u003cp\u003eAdjustable parallels are used when a fixed parallel set does not provide the exact height needed for a particular workpiece. This set suits horizontal milling, surface grinding, and inspection setups where consistent, repeatable workpiece elevation is required. The adjustable design reduces the number of individual parallels a shop must stock while still delivering precise, reliable support across a broad range of heights. The 6-piece configuration covers multiple height combinations simultaneously, supporting efficient multi-part or multi-operation setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable range from 3\/8 to 2-1\/4 inches accommodates a wide variety of workpiece heights\u003c\/li\u003e\n  \u003cli\u003eOverall lengths available: 1.75 inches, 2.13 inches, 2.69 inches, and 3.56 inches across the set\u003c\/li\u003e\n  \u003cli\u003e5-1\/16 inch body length fits standard milling vises and surface grinder setups\u003c\/li\u003e\n  \u003cli\u003e9\/32 inch thickness provides a slim profile for tight workholding clearances\u003c\/li\u003e\n  \u003cli\u003e6-piece set covers multiple height and length combinations in a single purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose adjustable parallel set suitable for use with standard milling vises, surface grinders, and precision inspection setups in machining and metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAdjustable parallels are typically set and secured by a machinist or toolmaker before clamping the workpiece in the vise. Always verify the parallel is fully seated and locked at the desired height before applying clamping force. Clean parallel surfaces and vise beds before use to prevent measurement error or rocking. Handle precision parallels carefully to avoid nicks or burrs that could compromise flatness and accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Range\u003c\/strong\u003e: 3\/8 to 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Lengths in Set\u003c\/strong\u003e: 1.75 inches, 2.13 inches, 2.69 inches, 3.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 14-870-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715812098354,"sku":"14-870-0","price":142.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b01c10ade7a8bc437d981d7e0048954a.jpg?v=1788518625","url":"https:\/\/voomisupply.com\/products\/spi-14-870-0-adjustable-parallel-set-6-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
