The HART COOLEY a618ms10x4 is an aluminum straight-blade, 4-way sidewall and ceiling register designed for residential and light commercial HVAC air distribution. The register features adjustable vertical fins that allow individual deflection control, letting the installer direct airflow in four directions to suit the room layout. A galvanized multi-shutter damper provides airflow volume control at the register face. Stamped-face margins eliminate mitered corners and rough edges for a clean, finished appearance. The bright white finish suits standard interior trim. HVAC installers and sheet metal contractors are the typical trade for this fitting.
This register is used in forced-air HVAC systems as a supply-air terminal at sidewall or ceiling duct openings. It suits residential new construction and retrofit applications where a surface-mounted register is needed on a standard rectangular duct rough-in. The 10-inch by 4-inch face size fits a common duct boot or collar opening. The adjustable fins and integrated multi-shutter damper make it appropriate for zoned rooms where both airflow direction and volume need to be set at the register level without additional damper hardware upstream.
Designed as an OEM-style supply register for residential and light commercial forced-air HVAC systems with a 10-inch by 4-inch rectangular duct opening or boot collar.
Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut down the air handler or furnace and confirm the system is not pressurized before cutting or fitting the duct opening. Secure the register to the wall or ceiling surface using the mounting holes on the stamped face frame. Adjust the fin deflection and damper position after system startup to balance airflow to the space.
