This component provides structural support where a chimney flue passes through a ceiling assembly, anchoring the venting system and maintaining proper clearance to combustibles at the ceiling plane. Licensed chimney installers and HVAC technicians install this part during new construction or retrofit chimney projects. The 6-inch diameter matches the DuraTech system's nominal flue sizing, ensuring a consistent fit within the chimney run.\u003c\/p\u003e\u003cp\u003eThis ceiling support box is used in residential and light commercial applications where a factory-built chimney system penetrates a framed ceiling. It is typically installed in wood-framed floor and ceiling assemblies and serves as a transition point between chimney sections, providing load-bearing support and fire-clearance compliance at the ceiling level. It is suited for installations following NFPA 211 and local building code requirements for factory-built chimney systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch diameter sizing compatible with DuraTech chimney system components\u003c\/li\u003e\n\u003cli\u003eProvides structural anchoring for the chimney flue at ceiling penetrations\u003c\/li\u003e\n\u003cli\u003eMaintains required clearance to combustibles at the ceiling assembly\u003c\/li\u003e\n\u003cli\u003eDesigned for use in wood-framed residential ceiling construction\u003c\/li\u003e\n\u003cli\u003eSupports proper alignment of chimney sections through the ceiling plane\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style component for use with 6-inch diameter DuraTech factory-built chimney systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified chimney installer or licensed contractor in accordance with NFPA 211 and applicable local building codes.
