Storm collars are installed where flue pipes, vent stacks, or duct penetrations pass through a roof deck, sealing the gap between the pipe and the roof flashing to prevent water intrusion. This collar is a standard component in residential and light commercial HVAC and venting installations. HVAC technicians and sheet metal contractors install this part as part of a complete roof penetration assembly. The hot dip galvanized finish provides corrosion resistance suited for outdoor and rooftop exposure.\u003c\/p\u003e\u003cp\u003eThis storm collar is used on 7-inch round duct or pipe penetrations through roof assemblies. Typical applications include B-vent flue terminations, single-wall exhaust vent stacks, and round sheet metal duct roof exits in residential and light commercial systems. It is a formed sheet metal component that wraps the pipe at the roof line, working in conjunction with roof flanges and pipe flashing to create a weathertight seal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot dip galvanized steel construction for corrosion resistance in outdoor rooftop conditions\u003c\/li\u003e\n\u003cli\u003e7-inch diameter round profile fits standard 7-inch duct and pipe penetrations\u003c\/li\u003e\n\u003cli\u003eFormed sheet metal design for consistent fitment and straightforward field installation\u003c\/li\u003e\n\u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal ductwork and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation storm collar for 7-inch round duct and vent pipe roof penetration assemblies in residential and light commercial HVAC and venting systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal contractor as part of a roof penetration venting assembly. The collar should be positioned snugly around the pipe at the roofline and sealed with an appropriate weatherproof sealant or caulk per manufacturer and SMACNA guidelines. Ensure the pipe and roof flashing assembly are properly secured before finalizing the storm collar position. Follow all applicable local mechanical codes and SMACNA standards for duct and vent roof penetration installations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 7 inches diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Storm Collar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 142_7IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283974521138,"sku":"142_7IN","price":21.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276982.jpg?v=1781064714","url":"https:\/\/voomisupply.com\/products\/southwark-metal-142_7in-storm-collar-7-inch-round","provider":"Voomi Supply","version":"1.0","type":"link"}
