Built around a 2-1\/4 inch wrench size, it features a 4-7\/32 inch head diameter and a 1\/2 inch head thickness, making it suited for fasteners in confined or obstructed spaces where a standard open end wrench cannot reach. The chrome-plated finish resists corrosion and simplifies cleanup after use. This tool is intended for professional mechanics, maintenance technicians, and trade pros working in industrial, commercial, or heavy equipment environments where access is restricted.\u003c\/p\u003e\u003cp\u003eOpen end crowfoot wrenches are used when a conventional wrench or socket cannot access a fastener due to surrounding components, tubing, or housing. The J5372CF fits standard 1\/2 inch drive extensions and torque wrenches, making it a practical solution for torque-critical applications such as plumbing fittings, hydraulic line connections, and mechanical assembly work where precise torque application is required in tight quarters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-1\/4 inch wrench size for larger fasteners and fittings\u003c\/li\u003e\n\u003cli\u003e4-7\/32 inch head diameter for clearance around obstructed fastener areas\u003c\/li\u003e\n\u003cli\u003e1\/2 inch head thickness for low-profile access in confined spaces\u003c\/li\u003e\n\u003cli\u003eChrome-plated finish for corrosion resistance and easy maintenance\u003c\/li\u003e\n\u003cli\u003eCompatible with standard 1\/2 inch drive torque wrenches and extensions\u003c\/li\u003e\n\u003cli\u003eLifetime warranty coverage from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2 inch drive torque wrenches, breaker bars, and ratchets.

When using with a torque wrench at an angle offset from 0 degrees, apply the appropriate torque correction factor per the torque wrench manufacturer guidelines. Ensure the fastener and fitting threads are clean and free of debris before applying torque. This tool should be installed and used by qualified mechanics or maintenance technicians familiar with torque application procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 4-7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 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: 1.213 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: J5372CF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541532049714,"sku":"J5372CF","price":121.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d08eeaa265305a67ce9419f9b1ca2c6.jpg?v=1785878570","url":"https:\/\/voomisupply.com\/products\/proto-j5372cf-open-end-crowfoot-wrench-2-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
