The RECTORSEAL 210VM-12X6 is a stamped steel vertical single deflection supply grille with an integrated multi-shutter damper, designed for ceiling and sidewall HVAC supply air applications. The adjustable vertical blades allow directional airflow control in a single plane, set during installation or system balancing. The multi-shutter damper provides field-adjustable volume control without requiring separate balancing hardware. The 12 x 6 inch face dimension fits standard rectangular duct openings, and the white powder-coated finish delivers corrosion resistance and long-term appearance retention in residential and light commercial environments.
This grille is suited for residential and light commercial HVAC systems where controlled supply air direction and built-in airflow balancing are required. Typical installations include sidewall and ceiling supply registers connected to rectangular duct branches in forced-air heating and cooling systems. The single deflection blade configuration directs air in one plane, making it appropriate for rooms where horizontal or vertical throw needs to be set and held at a fixed angle.
Designed as an OEM-style replacement or new-install supply grille for residential and light commercial forced-air HVAC systems using standard rectangular duct openings.
Installation is typically performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling system before cutting into ductwork or mounting the grille. Secure the grille to the wall, ceiling, or duct collar using appropriate fasteners for the substrate. Adjust blade angle and damper position after system startup to achieve the desired airflow direction and volume balance.
