It features a dual-mount design with both a plate base and a stud mount, allowing flexible installation in equipment support applications. The isolator measures 3.125 inches in diameter and 1.5 inches in height, with a 1\/2-13 threaded stud that extends 1.625 inches. It is used to reduce vibration transmission between mechanical equipment and supporting structures. HVAC technicians and mechanical contractors install this type of isolator under compressors, fan assemblies, pumps, and similar rotating equipment to protect connected structures from vibration-induced fatigue and noise.\u003c\/p\u003e\u003cp\u003eThis isolator is suited for residential and light commercial HVAC, refrigeration, and mechanical systems where equipment vibration must be isolated from floors, curbs, platforms, or equipment rails. The plate\/stud configuration supports installations requiring a bolted-down base plate combined with a threaded stud connection to the supported equipment. At 980 pounds capacity, it handles loads typical of rooftop units, condensing units, and small to mid-size pump assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e980 lb maximum load capacity for heavy equipment support\u003c\/li\u003e\n\u003cli\u003eCombination plate and stud mount for dual-side installation flexibility\u003c\/li\u003e\n\u003cli\u003e1\/2-13 threaded stud with 1.625 inch thread length\u003c\/li\u003e\n\u003cli\u003eRound profile, 3.125 inches diameter and 1.5 inches high for compact footprint\u003c\/li\u003e\n\u003cli\u003eDesigned to reduce structure-borne vibration and noise transmission\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation vibration isolator for mechanical equipment requiring a plate\/stud mount configuration with a 1\/2-13 thread size and up to 980 lb load capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis isolator is typically installed by licensed HVAC technicians or mechanical contractors during equipment mounting or scheduled maintenance. De-energize and lock out the equipment before removing or installing isolators. Verify the combined load per isolator does not exceed the 980 lb rated capacity when distributing the equipment weight across multiple mounts. Follow local mechanical codes for vibration isolation requirements on rooftop and pad-mounted equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Load Capacity\u003c\/strong\u003e: 980 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolator Type\u003c\/strong\u003e: Plate\/Stud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Stud and Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TECH PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51551-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECH PRODUCTS","offers":[{"title":"Default Title","offer_id":67918935228722,"sku":"51551-4","price":72.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f1cc4cd2994b164c6a7ac201d319af4.jpg?v=1791274716","url":"https:\/\/voomisupply.com\/products\/tech-products-51551-4-vibration-isolator-980-lb-plate-stud","provider":"Voomi Supply","version":"1.0","type":"link"}
