The crowfoot head attaches to a standard 3\/8 inch drive ratchet or torque wrench, making it a practical addition to any professional tool kit. The head measures 2.156 inches in diameter and 0.38 inches thick, keeping the profile low for tight clearances. A chrome-plated finish provides corrosion resistance for long service life in shop and field conditions.\u003c\/p\u003e\n\u003cp\u003eThis crowfoot wrench is used across trades wherever a 1-1\/4 inch fastener must be turned in a restricted or angled location. Common applications include HVAC equipment service, plumbing line connections, and mechanical assembly work where open-end access is required but a full wrench swing is not available. The 3\/8 inch drive compatibility makes it easy to pair with existing ratchets, extensions, and torque wrenches already in a technician's kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch open end size fits standard hex fasteners and fittings\u003c\/li\u003e\n  \u003cli\u003eLow-profile head at 0.38 inches thick for tight clearance applications\u003c\/li\u003e\n  \u003cli\u003e2.156 inch head diameter for proper socket drive engagement\u003c\/li\u003e\n  \u003cli\u003eChrome-plated finish for corrosion resistance and easy cleaning\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty backed by the manufacturer\u003c\/li\u003e\n  \u003cli\u003eAttaches to standard 3\/8 inch drive ratchets and torque wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8 inch drive ratchets, extensions, and torque wrenches.

When using with a torque wrench at an angle offset from the fastener centerline, consult torque correction factor guidelines to maintain accurate torque values. Inspect the chrome finish and drive socket for wear or damage before each use. This tool is intended for hand-tool use only and should not be used with impact drivers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 1-1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.156 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: 0.24 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: J4940CF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542923444530,"sku":"J4940CF","price":61.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e87f39d3b0cd39f89ab2be85eef75c.jpg?v=1785911115","url":"https:\/\/voomisupply.com\/products\/proto-j4940cf-open-end-crowfoot-wrench-1-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
