This stainless steel attachment mounts to the caliper and enables accurate depth measurements in bores, slots, and stepped surfaces. It is a precision measurement tool used by machinists, tool and die technicians, pipefitters, and HVAC fabrication professionals who require verified depth readings during layout and inspection work. At 0.5 pounds, it is lightweight and easy to handle in tight workspaces. The 65100 is sold individually and is intended as a direct add-on accessory to an existing compatible caliper.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 65100 depth attachment is suited for shop-floor and field measurement applications where standard caliper jaws cannot reach into recessed areas. It is commonly used in light manufacturing, mechanical contracting, and precision maintenance environments. Typical applications include measuring bore depth on pipe fittings, checking slot depth on fabricated sheet metal components, and performing layout verification on mechanical assemblies. The attachment works with the 120 and 120M Series dial calipers in the 12 inch (300 mm) range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction for durability and resistance to corrosion in shop environments\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with 12 inch (300 mm) 120 and 120M Series STARRETT dial calipers\u003c\/li\u003e\n  \u003cli\u003eEnables depth measurement in bores, slots, and stepped surfaces beyond standard jaw reach\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.5 pounds for easy one-hand use\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for individual replacement or supplemental purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 12 inch (300 mm) STARRETT 120 and 120M Series dial calipers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or precision measurement technicians familiar with caliper accessories. Before attaching, ensure the caliper jaw faces and the attachment seating surfaces are clean and free of debris. Follow the caliper manufacturer instructions for proper attachment alignment and securing to avoid measurement error. No special tools or trade licensing is required, but accurate fitment should be confirmed before taking measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Depth Attachment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 12 inch (300 mm) 120 and 120M Series Dial Calipers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 65100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543236739378,"sku":"65100","price":169.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/771988ddee65b29b0beac3600e3bad6a.jpg?v=1785916739","url":"https:\/\/voomisupply.com\/products\/starrett-65100-caliper-depth-attachment-12-inch-dial-calipers","provider":"Voomi Supply","version":"1.0","type":"link"}
