The rod extends the measuring range of the depth gage, with a maximum measurement capacity of 2.0000 inches. It serves as an accessory component in precision measurement setups and is installed by machinists, tool-and-die technicians, quality control inspectors, and skilled tradespeople who require accurate depth readings in production or inspection environments. The rod type anvil design is consistent with the original 449 Series specification.\u003c\/p\u003e\n\u003cp\u003eThis rod is suited for precision depth measurement tasks in machine shops, manufacturing facilities, and inspection stations. It is used wherever a 449 Series micrometer depth gage requires an extended or replacement rod to measure depths up to 2 inches. The part is typically installed during routine maintenance of measurement tools or when expanding the measuring range of an existing 449 Series depth gage setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRod-type accessory designed to extend or replace the measuring rod on 449 Series micrometer depth gages\u003c\/li\u003e\n  \u003cli\u003eMaximum measurement capacity of 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003eAnvil type: Rod, consistent with 449 Series gage design requirements\u003c\/li\u003e\n  \u003cli\u003eSold individually, compatible with existing 449 Series depth gage configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Starrett 449 Series Micrometer Depth Gages, as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with precision measurement instruments. Before swapping rods, ensure the depth gage is clean and free of debris at the rod seating surfaces to maintain measurement accuracy. Follow the 449 Series gage manufacturer instructions for rod installation and removal to avoid damage to the gage body or rod threads. Verify calibration after any rod change before returning the instrument to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Rod\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 449 Series Micrometer Depth Gages\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 71839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544615125298,"sku":"71839","price":43.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c860af8e4e5467fd9dcdb06a3eb1275.jpg?v=1785931536","url":"https:\/\/voomisupply.com\/products\/starrett-71839-micrometer-rod-2-inch-449-series-depth-gage","provider":"Voomi Supply","version":"1.0","type":"link"}
