The RECTORSEAL 210VM12X8 is a vertical single deflection supply grille with an integrated multi-shutter damper, designed for ceiling and sidewall supply applications in residential and light commercial HVAC systems. Constructed from stamped steel with a white powder coat finish, this grille fits larger rectangular duct openings where increased airflow capacity is required. The vertical single deflection blade configuration provides directional control in one plane, while the multi-shutter damper allows airflow volume adjustment directly at the grille face without additional hardware. Licensed HVAC technicians and sheet metal installers work with this type of register as part of supply-side air distribution systems.
This grille is suited for residential and light commercial forced-air HVAC installations where adjustable airflow direction and volume control are needed at the supply outlet. The 12 inches by 8 inches face size accommodates larger rectangular duct openings common in main trunk branch applications. Ceiling and sidewall mounting are both supported, making this unit flexible for various duct layout configurations. The white powder coat finish integrates cleanly with standard interior finishes.
Designed as an OEM-style replacement or new-installation supply grille for residential and light commercial forced-air HVAC systems with rectangular duct openings requiring a 12 inches by 8 inches grille face.
Installation is typically performed by a licensed HVAC technician or qualified sheet metal installer. Power down the air handling unit and close the system dampers before removing an existing grille or fitting a new one. Verify the rough duct opening dimensions match the grille neck size before fastening. Follow local mechanical codes and manufacturer framing guidelines for proper screw placement into surrounding drywall or ceiling material.
