Both ends feature 12-point profiles, giving the technician the ability to engage hex fasteners at 30-degree increments for repositioning in confined areas. Constructed from steel, this wrench fits 9\/16-inch and 5\/8-inch fasteners. It is a non-ratcheting tool intended for hand-torque applications. Electricians, HVAC technicians, and plumbers use obstruction wrenches when fastener clearance is limited by surrounding structure, enclosures, or adjacent components.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for service work on equipment with deeply recessed or partially obstructed fasteners, such as panel interiors, mechanical equipment rooms, and tight mechanical assemblies. The double-end configuration provides two commonly paired fastener sizes in one tool, reducing the need to swap wrenches during a job. It is appropriate for residential and light commercial trade applications where 9\/16-inch and 5\/8-inch hex fasteners are standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design with 9\/16-inch and 5\/8-inch openings for two fastener sizes in one tool\u003c\/li\u003e\n\u003cli\u003e12-point box end profile allows 30-degree arc swing for repositioning in restricted spaces\u003c\/li\u003e\n\u003cli\u003eObstruction-style offset head clears surrounding structure near recessed fasteners\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under hand-torque loads\u003c\/li\u003e\n\u003cli\u003eNon-ratcheting design for straightforward fastener engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard obstruction box end wrench for 9\/16-inch and 5\/8-inch hex fasteners in trade and mechanical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is a hand tool used by licensed HVAC technicians, electricians, plumbers, and general trade professionals. Always de-energize and lock out electrical equipment before using any hand tool inside enclosures or panels. Confirm fastener size before applying torque to avoid rounding. Do not extend the handle with a pipe or cheater bar, as this is a hand-torque tool without a rated extension provision.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Obstruction Box End Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Sizes\u003c\/strong\u003e: 9\/16 inches and 5\/8 inches\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\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: J1730\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544231805234,"sku":"J1730","price":46.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6d48ae72cdf8218e5e6e872d61e7757.jpg?v=1785926028","url":"https:\/\/voomisupply.com\/products\/proto-j1730-obstruction-box-end-wrench-9-16-x-5-8-in-12-pt","provider":"Voomi Supply","version":"1.0","type":"link"}
