It attaches to a standard ratchet or extension via a square drive socket, allowing access to nuts and fittings in confined spaces where a standard open-end wrench cannot reach. The head measures 2.59 inches in diameter and 0.38 inches thick, keeping the profile low for tight clearance work. A chrome-plated finish resists corrosion and makes cleaning straightforward after use in greasy environments. This tool is built to inch measurements and carries a lifetime warranty.\u003c\/p\u003e\n\u003cp\u003eThe J4950CF is suited for use in automotive, HVAC, plumbing, and industrial maintenance applications where accessibility to fasteners is restricted by adjacent components or framing. It is commonly used by HVAC technicians torquing flare nuts on refrigerant lines, plumbers working compression fittings in tight spaces, and mechanics accessing fasteners behind engine components. The crowfoot design integrates with any matching square-drive torque wrench, ratchet, or extension bar.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-9\/16 inch wrench size for precise fastener fit\u003c\/li\u003e\n  \u003cli\u003eHead diameter of 2.59 inches with a low-profile 0.38 inch head thickness for tight clearance access\u003c\/li\u003e\n  \u003cli\u003eChrome-plated finish for corrosion resistance and easy cleaning\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard square-drive ratchets, extensions, and torque wrenches\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for use with standard SAE fasteners\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard square-drive ratchets and torque wrenches.

Before use, ensure the square drive size of the crowfoot matches the ratchet or torque wrench being used. When applying torque with a crowfoot wrench at an angle, consult torque wrench correction factor guidelines to maintain accuracy. Keep the drive and fastener aligned as closely as possible to avoid rounding the fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 1-9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J4950CF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542803644722,"sku":"J4950CF","price":73.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f786f1b6a2ae9d18d169e291b02d6de8.jpg?v=1785907887","url":"https:\/\/voomisupply.com\/products\/proto-j4950cf-open-end-crowfoot-wrench-1-9-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
