Measuring 1\/4 inch in diameter by 1-3\/8 inches in width by 4 inches in length, this U-bolt delivers corrosion resistance through its zinc plating, making it suitable for both indoor and light-duty outdoor installations. Sold in bulk packs of 5 units, it suits contractors and technicians who need reliable fasteners on hand for service calls and installations.\u003c\/p\u003e\n\u003cp\u003eThis U-bolt is used wherever pipe, conduit, tubing, or structural members need to be clamped or secured to a flat surface or support. Typical applications include pipe hangers, conduit straps, tube clamps, and light structural mounting in residential and commercial mechanical systems. The 4-inch leg length accommodates a range of pipe diameters and mounting depths, while the 1-3\/8-inch inner width targets standard small-diameter pipe and tubing. Electricians, plumbers, HVAC technicians, and general contractors commonly use this fastener type during rough-in and finish work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e146-grade zinc plating provides corrosion resistance for indoor and light-duty outdoor use\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch diameter threaded rod legs for standard nut and washer hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e4-inch leg length accommodates a range of pipe sizes and mounting configurations\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-inch inner width suited for small-diameter pipe and tubing clamping\u003c\/li\u003e\n  \u003cli\u003eBulk pack of 5 units per package reduces per-unit cost for service and installation work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose zinc U-bolt for pipe, conduit, and tube clamping applications in residential and commercial mechanical installations.

Power down or shut off the relevant system before securing conduit, pipe, or tubing runs. Use appropriately rated nuts and washers with 1\/4-inch thread, and follow applicable code requirements under the NEC, IPC, or IFGC for fastener spacing and support intervals. Do not overtighten, as this can deform the pipe or tubing being clamped.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Width\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeg Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 146\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.73 pounds\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 MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N222-117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51559765213490,"sku":"N222-117","price":16.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e00a202f65dc18f8cb336ff3cb5d67f4.jpg?v=1786440392","url":"https:\/\/voomisupply.com\/products\/national-mfg-n222-117-zinc-u-bolt-1-4x1-3-8x4-in-146","provider":"Voomi Supply","version":"1.0","type":"link"}
