Built from steel with a chrome finish, it features 12-point box ends sized at 1\/4 inch and 5\/16 inch. The ratcheting mechanism allows the user to drive fasteners without breaking contact with the fastener head, reducing repositioning time in confined areas. This wrench is appropriate for HVAC technicians, plumbers, electricians, and general mechanical trades who require a compact, dual-size hand tool for service and installation work.\u003c\/p\u003e\n\u003cp\u003eThe J1191T-A suits residential and light commercial service applications where 1\/4 inch and 5\/16 inch fasteners are common — including sheet metal screws, valve packing nuts, electrical panel hardware, and equipment access panel fasteners. Its double-end configuration eliminates the need to carry two separate wrenches for adjacent fastener sizes. The chrome finish resists corrosion in wet or humid environments typical of HVAC and plumbing service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRatcheting box end allows continuous driving without lifting off the fastener\u003c\/li\u003e\n  \u003cli\u003eDouble-end design covers both 1\/4 inch and 5\/16 inch fastener sizes in one tool\u003c\/li\u003e\n  \u003cli\u003e12-point box profile provides multiple engagement positions in restricted swing areas\u003c\/li\u003e\n  \u003cli\u003eChrome finish on steel construction resists corrosion during service in humid or wet environments\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty coverage from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hand tool replacement suitable for trade use with 1\/4 inch and 5\/16 inch hex fasteners across HVAC, plumbing, electrical, and general mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wrench is a hand tool requiring no power source or special installation. Before servicing any equipment, follow lockout\/tagout procedures, shut off all electrical power, and close applicable gas or water supply valves. Use the correct size end to avoid rounding fastener heads, and confirm the ratcheting mechanism engages cleanly before applying torque. Inspect the tool for visible damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Box End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSizes\u003c\/strong\u003e: 1\/4 inch x 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: J1191T-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51539616399666,"sku":"J1191T-A","price":30.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce1ef89476c4ca3bdc096b3779a05cb5.jpg?v=1785843465","url":"https:\/\/voomisupply.com\/products\/proto-j1191t-a-box-end-wrench-1-4-x-5-16-in-12-point","provider":"Voomi Supply","version":"1.0","type":"link"}
