Manufactured from C-1010 steel with a zinc-plated finish for corrosion resistance, this U-bolt fits 2-1\/2 inch pipe and features a 1\/2-13 UNC thread with a 3 inch thread length. The overall length measures 5-7\/32 inches and the width is 2-15\/16 inches. Four nuts are included. This fastener is installed without a mount plate, making it suitable for direct structural attachment. Plumbers, pipefitters, and mechanical contractors commonly use this type of U-bolt for pipe hangers and support brackets in both new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThe GIB51535 is suited for residential and commercial mechanical systems where 2-1\/2 inch pipe requires secure, fixed support. Typical applications include water supply lines, HVAC refrigerant piping support, hydronic piping, and general mechanical piping runs. The zinc-plated finish provides adequate protection in dry and semi-exposed indoor environments. This U-bolt is used wherever a round-profile, threadrod-style pipe restraint is required on standard 2-1\/2 inch nominal pipe.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound profile fits 2-1\/2 inch nominal pipe securely\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread standard with 3 inch thread length for adequate fastening depth\u003c\/li\u003e\n  \u003cli\u003eC-1010 steel construction for reliable tensile strength in pipe support duty\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in indoor and semi-exposed applications\u003c\/li\u003e\n  \u003cli\u003eIncludes four nuts — no additional hardware required for basic installation\u003c\/li\u003e\n  \u003cli\u003eNo mount plate configuration for direct structural or strut-channel attachment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation U-bolt for 2-1\/2 inch nominal pipe support applications in mechanical, plumbing, and HVAC piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or mechanical contractors. Ensure the supporting structure or strut channel is rated for the pipe load before torquing fasteners. Follow applicable IPC and IFGC guidelines for pipe support spacing and hardware requirements. Do not overtighten the nuts in a way that deforms the pipe wall, and verify the zinc-plated finish is appropriate for the environment before installing in wet or corrosive conditions.\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\u003eMount Type\u003c\/strong\u003e: Without Mount Plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Pipe Size\u003c\/strong\u003e: 2-1\/2 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\u003eOverall Length\u003c\/strong\u003e: 5-7\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-15\/16 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: Zinc-Plated\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: 0.71 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: GIB51535\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51714342682930,"sku":"GIB51535","price":27.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d8fb8fbc0e484ebb4e0e34ade2e0184.jpg?v=1788499862","url":"https:\/\/voomisupply.com\/products\/gibraltar-gib51535-round-u-bolt-1-2-13-unc-2-1-2-inch-pipe","provider":"Voomi Supply","version":"1.0","type":"link"}
