This sheet metal fitting creates a secure transition point where round duct connects to a ductboard plenum or trunk line. The crimped end seats firmly into the ductboard cutout, while the straight collar end accepts flexible duct or rigid round pipe. HVAC sheet metal installers and duct fabricators use this collar during new construction and system retrofit work to maintain airtight connections at supply or return takeoffs.\u003c\/p\u003e\u003cp\u003eThis collar is suited for residential and light commercial HVAC applications where ductboard is the primary trunk or plenum material. It accommodates ductboard panels ranging from 1 inch to 1.5 inches in thickness, making it compatible with the most common ductboard dimensions used in forced-air systems. The 6-inch crimped shank provides sufficient depth for a reliable, foil-taped connection that meets typical duct sealing requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch collar diameter for standard round duct connections\u003c\/li\u003e\n\u003cli\u003e6-inch crimped shank length for secure ductboard insertion\u003c\/li\u003e\n\u003cli\u003eCompatible with 1-inch and 1.5-inch ductboard panel thicknesses\u003c\/li\u003e\n\u003cli\u003eCrimped end design allows flex duct or rigid pipe to slip over the collar end\u003c\/li\u003e\n\u003cli\u003eSheet metal construction for durability in low-pressure supply and return systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-inch to 1.5-inch ductboard panels in residential and light commercial forced-air HVAC duct systems requiring a 4-inch round collar takeoff.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified duct fabricators. Power down the air handling equipment and relieve any system pressure before cutting into an existing ductboard plenum. Insert the crimped shank through the ductboard cutout and seal all edges with UL 181-rated foil tape or mastic per applicable mechanical codes. Do not exceed the pressure rating of the ductboard system when sizing takeoffs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrimped Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Ductboard Thickness\u003c\/strong\u003e: 1 inch to 1.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SEAL-TITE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1727-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51345904402738,"sku":"1727-04","price":18.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554496.jpg?v=1782066058","url":"https:\/\/voomisupply.com\/products\/seal-tite-1727-04-ductboard-collar-4-in-6-in-crimped","provider":"Voomi Supply","version":"1.0","type":"link"}
