It covers fasteners from 3\/8 inch through 7\/8 inch in standard SAE sizes, giving technicians a compact set for reaching nuts and fittings in tight or obstructed spaces where a standard open-end wrench cannot seat. Crowfoot wrenches are a standard tool in HVAC, plumbing, and mechanical service work, particularly when accessing hard-to-reach fittings on refrigerant lines, fuel lines, and hydraulic connections. The set weighs 1.1 pounds, making it easy to carry in a service pouch or tool bag.\u003c\/p\u003e\u003cp\u003eThis crowfoot set is suited for residential and light commercial service applications. Technicians use crowfoot wrenches when working around valve bodies, union fittings, and compression connections where clearance prevents a box or combination wrench from engaging. The 3\/8 inch drive compatibility means the set works with the most common mid-size ratchets and torque wrenches already in a service technician's kit, allowing controlled torque application on sensitive fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9-piece set covering 3\/8 inch to 7\/8 inch SAE open end sizes\u003c\/li\u003e\n\u003cli\u003e3\/8 inch drive compatibility for use with standard ratchets, extensions, and torque wrenches\u003c\/li\u003e\n\u003cli\u003eOpen end crowfoot design accesses fasteners in restricted or obstructed spaces\u003c\/li\u003e\n\u003cli\u003eCompact set weight of 1.1 pounds for easy portability in a tool bag or pouch\u003c\/li\u003e\n\u003cli\u003eConsistent sizing increments across the range for complete fastener coverage in typical SAE service work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch drive crowfoot wrench set suitable for use with any 3\/8 inch drive ratchet, torque wrench, or extension bar in typical SAE mechanical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCrowfoot wrenches are installed by licensed HVAC technicians, plumbers, and mechanical service professionals. Before using on any fitting, ensure the system is depressurized, de-energized, or shut off as required by the relevant service procedure. Seat the crowfoot squarely on the fastener before applying torque to avoid rounding. When using with a torque wrench at an angle offset from zero degrees, apply the appropriate torque correction factor per standard mechanical practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Open End Crowfoot Wrench Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 3\/8 inch to 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\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: J49004CF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540448018738,"sku":"J49004CF","price":344.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bacbf8a60602802690c8f0172a2ff0.jpg?v=1785855465","url":"https:\/\/voomisupply.com\/products\/proto-j49004cf-9-pc-crowfoot-wrench-set-3-8-in-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
