Manufactured from C-1010 steel with a hot galvanized finish, this fastener resists corrosion in exposed or outdoor installations. The 1\/2-13 UNC thread runs 3 inches in length, providing ample engagement for standard hex nuts. Overall length is 8.5 inches with an inside width of 3.5 inches to accommodate standard 3-inch nominal pipe. Two nuts are included. Weighing 0.95 pounds, this U-bolt is suited for both new construction and retrofit pipe support applications.\u003c\/p\u003e\u003cp\u003eThis U-bolt is used in residential and commercial mechanical systems wherever 3-inch nominal pipe requires secure, code-compliant support. Common applications include HVAC refrigerant or hydronic piping, plumbing supply and drain lines, gas piping support, and conduit runs. It is installed without a mount plate, making it appropriate for through-rod or direct-attachment configurations on strut, beam clamps, or structural steel. Plumbers, pipefitters, and HVAC technicians working under IPC, IFGC, or ASHRAE piping support spacing guidelines will find this fitting suitable for standard support-interval installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound U-bolt profile sized for 3-inch nominal pipe with 3.5-inch inside width\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread standard with 3-inch thread length for reliable nut engagement\u003c\/li\u003e\n\u003cli\u003eC-1010 steel construction with hot galvanized finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eOverall length of 8.5 inches accommodates insulated or bare pipe installations\u003c\/li\u003e\n\u003cli\u003eIncludes two nuts — no additional hardware required for basic installation\u003c\/li\u003e\n\u003cli\u003eNo mount plate design for direct rod or structural attachment configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install pipe support fastener for 3-inch nominal pipe in standard inch-measurement piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Shut off and depressurize the pipe system before adjusting or repositioning any support hardware. Tighten nuts evenly to avoid cocking the U-bolt on the pipe, which can cause stress concentrations or damage to pipe coatings. Follow applicable code requirements for pipe support spacing and hanger material compatibility, particularly when installing in corrosive or high-humidity environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Without Mount Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Pipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Width\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C-1010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 2 Nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GIB53107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722357211442,"sku":"GIB53107","price":40.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f6517f491c24ffcec5178a1c788a908_595d508e-3876-4c04-863a-dad48cff3357.jpg?v=1788589959","url":"https:\/\/voomisupply.com\/products\/gibraltar-gib53107-round-u-bolt-3-inch-pipe-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
