Part of the National catalog 2190 series, this U bolt measures 0.25 inches in rod diameter, 1.125 inches in inside width, and 3.5 inches in thread length. It ships with a plate and two hex nuts included. The zinc finish provides corrosion resistance suitable for light-duty indoor and outdoor environments. Licensed tradespeople and skilled DIYers install this hardware wherever a secure, removable pipe or structural clamp is needed without welding or permanent fastening.\u003c\/p\u003e\n\u003cp\u003eThis U bolt is well suited for securing pipe runs in plumbing rough-in work, mounting exhaust or fuel lines in automotive repair, and general-purpose strapping of conduit, hose, or rod stock to structural members. The listed pipe size refers to the inside diameter of standard pipe, so technicians should match the 1.125-inch inside width to the outside diameter of the pipe being clamped when selecting this part. It is sold individually with hardware included.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZinc-plated steel construction for corrosion resistance in light-duty applications\u003c\/li\u003e\n  \u003cli\u003ePlate and two hex nuts included — no separate hardware purchase needed\u003c\/li\u003e\n  \u003cli\u003eRound-bend profile distributes clamping load evenly around pipe OD\u003c\/li\u003e\n  \u003cli\u003eSuitable for pipe, wood, and structural fastening in plumbing, automotive, and industrial settings\u003c\/li\u003e\n  \u003cli\u003ePart of the National 2190 catalog series for consistent cross-reference ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose U bolt for use on standard pipe, conduit, and structural members where a 0.25-inch rod diameter, 1.125-inch inside width round U bolt is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers, HVAC technicians, electricians, and automotive technicians depending on the application. Always de-energize, depressurize, or drain the system before securing or repositioning pipe clamps. Hand-tighten the hex nuts evenly before applying a wrench to avoid cocking the plate. Do not overtighten on thin-wall or plastic-lined pipe, as the round U bolt concentrates load at the bend point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Width\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel with zinc plating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Included\u003c\/strong\u003e: Plate and hex nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.127 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00038613125766\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: NATIONAL MARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N222109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51343787000114,"sku":"N222109","price":16.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550445.jpg?v=1782024534","url":"https:\/\/voomisupply.com\/products\/national-marker-n222109-zinc-round-u-bolt","provider":"Voomi Supply","version":"1.0","type":"link"}
