The worm gear drive mechanism allows precise tightening across a consistent clamping range, delivering a secure, leak-resistant seal at duct joints and transitions. The galvanized finish provides corrosion resistance in both indoor and light-duty exposed installations. This clamp is a standard fastening component installed by HVAC technicians, sheet metal workers, and mechanical contractors during new construction and service work.\u003c\/p\u003e\u003cp\u003eThis clamp is well suited for residential and light commercial HVAC and ventilation applications where flexible duct collars, exhaust connectors, or tubing transitions require a reliable mechanical seal. It is commonly used at air handler connections, dryer vent transitions, bathroom exhaust fan outlets, and other 3-inch duct or hose terminations. The package quantity of 50 units per pack makes it practical for stocking in service vehicles or shop inventory for ongoing installation and maintenance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch nominal size fits standard 3-inch flexible duct and hose connections\u003c\/li\u003e\n\u003cli\u003eGalvanized steel construction resists corrosion in typical mechanical system environments\u003c\/li\u003e\n\u003cli\u003eWorm gear drive allows controlled, even tightening for a secure seal\u003c\/li\u003e\n\u003cli\u003eSold in a 50-unit pack suitable for stocking and bulk installation use\u003c\/li\u003e\n\u003cli\u003eCompatible with standard flexible duct collars, exhaust tubing, and hose fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-use clamp for 3-inch flexible duct, exhaust hose, and tubing connections in residential and light commercial HVAC and ventilation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or mechanical contractor. Power down or de-energize associated equipment before making duct or hose connections. Use an appropriate nut driver or flat-blade screwdriver to drive the worm gear to proper tightness without overtightening, which can deform flexible duct collars. Follow applicable local mechanical codes and manufacturer duct installation guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Clamp Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 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\u003ePackage Weight\u003c\/strong\u003e: 4.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAMBRO INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51524575035698,"sku":"283","price":99.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90be4a926ea14bdab7458f2b446d68be.jpg?v=1785452130","url":"https:\/\/voomisupply.com\/products\/lambro-industries-283-galvanized-worm-gear-clamp-3-in-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
