It covers a measurement range of 0 to 36 inches with an accuracy of 0.0005 inches and a graduation of 0.001 inches, making it suitable for applications that demand tight dimensional verification. The caliper features a satin chrome finish, double set screws for beam lock, and a fine adjustment mechanism for controlled positioning. It is used by machinists, HVAC sheet metal fabricators, pipefitters, and other trade professionals who require reliable large-range measurement capability. The unit ships with a protective case.\u003c\/p\u003e\n\u003cp\u003eThe 50530 is built for both inside and outside measurements across a 36-inch span. The 3-inch jaw depth accommodates workpieces with significant depth or offset, and the 0.5-inch nib size provides clearance for inside-diameter work on larger bores. It is well suited for fabrication shops, pipe measurement, ductwork layout, and any field or bench application where a standard 6-inch or 12-inch caliper falls short in range. Fine adjustment allows the technician to dial in the reading without overshoot, which is critical at this scale.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 0 to 36 inches covers large-format workpieces and assemblies\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0005 inches with 0.001-inch graduation for precise dimensional readings\u003c\/li\u003e\n  \u003cli\u003eFine adjustment mechanism enables controlled, repeatable positioning of the sliding jaw\u003c\/li\u003e\n  \u003cli\u003eDouble set screws lock the beam securely once the measurement is set\u003c\/li\u003e\n  \u003cli\u003e3-inch jaw depth handles deep-set features and offset workpieces\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish on steel construction reduces glare and resists surface corrosion\u003c\/li\u003e\n  \u003cli\u003eIncludes a protective carrying case for storage and transport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose large-range vernier caliper for bench and field measurement tasks requiring inside and outside measurement capability up to 36 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eVernier calipers require no installation but should be zeroed and inspected for jaw parallelism before use. Keep the measuring faces clean and free of chips or debris, as contamination at this scale of measurement will introduce error. Store the caliper in the included case when not in use to protect the beam and jaw faces. Calibration should be verified periodically against a traceable standard in accordance with your shop quality procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Types\u003c\/strong\u003e: Inside and outside measurement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNib Size\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliper Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Screws\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFine Adjustment\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Inside Diameter Jaws\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Depth Measurement Rod\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.125 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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50530\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540338802994,"sku":"50530","price":3961.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2daf3fd0e58d15e1e3abca666e7e31a.jpg?v=1785852625","url":"https:\/\/voomisupply.com\/products\/starrett-50530-vernier-caliper-0-to-36-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
