Manufactured from C1010 steel with a zinc-plated finish for corrosion resistance, this U-bolt is sized for 4-inch pipe with a 1\/2-13 UNC thread and a 3-inch thread length. The overall length measures 6.75 inches with a width of 4.5625 inches. It ships without a mount plate and includes four nuts, making it ready for straightforward installation on strut channel, beam clamps, or similar support structures. Weighing 0.89 pounds, this is a standard trade-grade fastener for pipe hangers and mechanical support work.\u003c\/p\u003e\n\u003cp\u003eThis U-bolt is suited for securing 4-inch pipe runs in commercial and residential mechanical systems, including HVAC piping, hydronic systems, plumbing supply and drain lines, and general industrial piping. It is intended for installation by licensed plumbers, pipefitters, and HVAC mechanics where a round U-bolt without a mount plate is specified. The zinc-plated steel construction is appropriate for dry and mildly corrosive indoor environments typical of mechanical rooms and utility spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized for 4-inch pipe with 4.5625-inch inside width\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread standard with 3-inch thread length\u003c\/li\u003e\n  \u003cli\u003eC1010 steel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eShips without mount plate for use with existing support hardware\u003c\/li\u003e\n  \u003cli\u003eIncludes four nuts for complete fastening without additional hardware\u003c\/li\u003e\n  \u003cli\u003eOverall length of 6.75 inches for adequate engagement on strut or mounting surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pipe support fastener for 4-inch pipe in mechanical, plumbing, and HVAC piping support applications where a round U-bolt with 1\/2-13 UNC thread is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers or pipefitters following applicable IPC and IFGC support spacing requirements. Depressurize and isolate the pipe run before positioning the U-bolt and tightening the supplied nuts. Do not overtighten the nuts against plastic-lined or soft pipe to avoid deformation of the pipe wall. Ensure the mounting structure is rated for the load of the supported pipe and its contents.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Pipe Size\u003c\/strong\u003e: 4 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\u003eWidth\u003c\/strong\u003e: 4.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.75 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: C1010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Without Mount Plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 4 Nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.89 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GIB53250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51717182882098,"sku":"GIB53250","price":36.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cc3d4c1bbe50b3b7062e84cc2cd2463.jpg?v=1788536676","url":"https:\/\/voomisupply.com\/products\/gibraltar-gib53250-round-u-bolt-4-inch-pipe-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
