Fabricated from hot dip galvanized steel, this offset starting collar connects a main trunk duct to a branch run, providing a transition point at the beginning of a duct run. The 16 inch by 8 inch sizing suits common residential and light commercial trunk configurations. HVAC sheet metal installers and ductwork fabricators use this fitting to establish a tight, code-compliant connection off the main trunk. The offset body pattern accommodates installations where straight takeoffs are not practical due to spatial constraints.\u003c\/p\u003e\n\u003cp\u003eThis collar is used in forced-air ducted HVAC systems where branch duct runs originate from a rectangular main trunk. The starting collar application means this fitting is typically placed at the upstream end of a branch, directly off the trunk, rather than midrun. It is suited for residential new construction, light commercial buildouts, and duct retrofit projects where a 16 inch by 8 inch trunk connection is required. The offset body pattern is particularly useful in tight mechanical spaces where clearance limits a straight-line transition.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in HVAC duct environments\u003c\/li\u003e\n  \u003cli\u003eOffset body pattern accommodates space-restricted installation scenarios\u003c\/li\u003e\n  \u003cli\u003eStarting collar type positions the fitting at the originating end of a branch duct run\u003c\/li\u003e\n  \u003cli\u003e16 inch by 8 inch nominal size fits common rectangular trunk duct dimensions\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fitting fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard rectangular trunk duct systems in residential and light commercial forced-air HVAC installations conforming to ACCA and SMACNA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal worker. Shut down the air handling system and de-energize the air handler before cutting into any existing duct. Secure the collar to the trunk duct using sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant in accordance with local mechanical codes and SMACNA guidelines. Follow ACCA Manual D duct design requirements for proper branch sizing and airflow balancing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 16 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Pattern\u003c\/strong\u003e: Offset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Starting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 23_16X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283981271346,"sku":"23_16X8","price":48.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277131.jpg?v=1781064958","url":"https:\/\/voomisupply.com\/products\/southwark-metal-23_16x8-duct-collar-takeoff-16x8-offset","provider":"Voomi Supply","version":"1.0","type":"link"}
