It spans a measurement range of 1-3\/4 inches to 2-1\/4 inches, making it suitable for bridging gaps and supporting workpieces at consistent heights inside vises, fixtures, and jigs. At 5-1\/16 inches long and 9\/32 inches thick, the 50583 provides a stable, low-profile bearing surface that holds its position without rocking. Machinists and toolroom technicians rely on adjustable parallels like this one to achieve repeatable setups when milling, grinding, or inspecting part dimensions.\u003c\/p\u003e\u003cp\u003eThe STARRETT 50583 is used in machine shops, toolrooms, and precision metalworking environments. It is well suited for horizontal milling setups, surface grinding fixtures, and quality inspection stations where a rigid, adjustable support is needed. The slim 9\/32-inch thickness allows it to fit in tight vise openings without sacrificing the stability required for accurate work. This parallel is appropriate for both production and job-shop environments handling ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable range of 1-3\/4 inches to 2-1\/4 inches for flexible setup use\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and long service life under shop conditions\u003c\/li\u003e\n\u003cli\u003e5-1\/16 inches overall length provides a wide bearing surface\u003c\/li\u003e\n\u003cli\u003e9\/32-inch thickness fits tight vise openings and compact fixtures\u003c\/li\u003e\n\u003cli\u003eLow-profile design supports consistent, repeatable workpiece positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose adjustable parallel for use in standard machinists vises, grinding fixtures, and layout setups requiring a 1-3\/4 inch to 2-1\/4 inch support range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAdjustable parallels are set by hand prior to clamping the workpiece. Always verify the parallel is fully seated and does not shift before applying vise pressure. Clean mating surfaces before use to prevent inaccurate seating caused by chips or debris. No special tools or certifications are required for use, but proper handling and storage protect the ground surfaces from damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/16 inches (128.59 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 9\/32 inches (7.14 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.28 inches (7 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541060911410,"sku":"50583","price":218.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cbba398a9a95a629bfc07145d0b6290.jpg?v=1785867991","url":"https:\/\/voomisupply.com\/products\/starrett-50583-adjustable-parallel-1-3-4-to-2-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
