The AMERICAN METAL PRODUCTS 400B10X12 is a gravity floor register designed for residential and light commercial forced-air HVAC systems. Measuring 10 inches by 12 inches, it installs flush into standard floor openings and relies on airflow pressure to open the damper vanes, eliminating the need for a manual operator. The register features heavy-weight painted steel bars in a brown finish and includes an adjustable damper for basic airflow control at the register level. HVAC installers and service technicians typically specify this type of register during new construction, system changeouts, or register replacement work.
This floor register is suited for installation in wood, tile, or carpeted floor surfaces where a gravity-operated damper is preferred over a lever-controlled design. The brown finish coordinates with common flooring materials and trim. At 10 inches by 12 inches, it fits a standard duct boot opening of that nominal size. It is appropriate for supply air applications in residential forced-air heating and cooling systems.
Designed as an OEM-style replacement or new-construction gravity floor register for standard 10 inch by 12 inch floor duct boot openings in residential forced-air HVAC systems.
Floor registers of this type are installed by HVAC technicians or general contractors during rough-in or finish work. Shut down the air handler or furnace before removing an existing register to avoid debris entry into the duct system. Drop the register into the floor opening and confirm the frame seats flush against the finished floor surface before finalizing placement. Follow local mechanical codes for register placement relative to furniture, walls, and return air pathways.
