The RECTORSEAL 803-6 is a galvanized steel duct ring designed to connect 6-inch round ductwork to ceiling diffusers or grilles in supply air applications. Constructed from galvanized steel, it provides corrosion resistance and structural integrity needed for long-term performance in both new construction and retrofit installations. This duct ring ensures a secure mechanical connection and consistent airflow transfer at the ceiling plane. HVAC technicians and sheet metal installers use this fitting as a standard transition component in residential and light commercial ceiling supply systems.
The 803-6 is suited for ceiling supply applications where 6-inch round duct terminates at a diffuser or grille. It is commonly installed in drop ceilings, drywall ceilings, and suspended grid systems during new construction rough-in or equipment replacement. The galvanized finish makes it appropriate for conditioned spaces where minor moisture exposure is a consideration.
Designed as an OEM-style replacement duct ring for 6-inch round duct ceiling supply diffuser and grille installations in residential and light commercial HVAC systems.
Installation is typically performed by a licensed HVAC technician or sheet metal installer. Shut down the air handling system before fitting or securing the duct ring to the ceiling opening. Ensure the duct ring is fully seated and sealed at the duct connection point to prevent air bypass. Follow local mechanical codes and manufacturer diffuser or grille instructions for fastening requirements.
