Built with a pear-head profile and 45 gear teeth, it delivers fine-increment ratcheting action suited to tight fastener work in mechanical, HVAC, plumbing, and electrical service environments. The overall length of 10.5 inches provides the leverage needed for standard torque applications without excessive bulk. The quick-release mechanism allows fast, one-hand socket changes, reducing downtime during multi-socket service calls. This tool is built to ASME B107.10 specification, confirming dimensional and performance compliance for professional use.\u003c\/p\u003e\n\u003cp\u003eThe J5449XLQR suits residential and commercial service work where a reliable 1\/2 inch drive ratchet is required. It is a practical choice for HVAC technicians removing compressor bolts, plumbers working on flange connections, and electricians handling panel and equipment hardware. The 10.5 inch handle length is well suited to open-bay and under-equipment access. The 45-tooth gear count means each swing requires only 8 degrees of arc, which is useful in confined spaces where full ratchet strokes are not possible.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch drive size compatible with standard 1\/2 inch drive sockets and accessories\u003c\/li\u003e\n  \u003cli\u003e45 gear teeth provide 8-degree arc swing for use in restricted spaces\u003c\/li\u003e\n  \u003cli\u003ePear-head design keeps the head profile compact for clearance-limited fasteners\u003c\/li\u003e\n  \u003cli\u003eQuick-release button enables one-hand socket removal and changes\u003c\/li\u003e\n  \u003cli\u003e10.5 inch overall length delivers leverage for standard torque demands\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B107.10 specification for professional-grade dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2 inch drive sockets, extensions, and adapters conforming to ASME B107.10 drive and square dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis ratchet is a hand tool and requires no installation. De-energize, isolate, and lock out equipment before using any hand tools on live mechanical or electrical systems. Inspect the ratchet head and quick-release mechanism before each use and remove from service if wear or damage is observed. Do not use extension bars or cheater pipes to increase leverage beyond the handle design intent.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Pear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.5 inches (266 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Gear Teeth\u003c\/strong\u003e: 45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.69 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eASME Specification\u003c\/strong\u003e: B107.10\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: J5449XLQR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542516793650,"sku":"J5449XLQR","price":154.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d24372cac2d45e167f64e9eb0f6fdd3b.jpg?v=1785902595","url":"https:\/\/voomisupply.com\/products\/proto-j5449xlqr-quick-release-ratchet-1-2-in-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
