The IMPERIAL RG3473 is a floor register designed for use in residential and light commercial forced-air HVAC systems. It covers a floor duct opening and directs conditioned air into the living space while providing a finished appearance at the floor level. The register ships as a single unit and weighs 0.85 pounds, making it straightforward to handle and position during installation. HVAC technicians and installers fit this register as part of new construction, renovation, or routine duct grille replacement work.
The RG3473 is suited for floor-mounted supply duct terminations in residential homes and light commercial spaces. It is installed at floor level over standard duct boot openings where conditioned air is delivered from a forced-air system. This register is sold as an individual unit, making it a practical option for single-opening replacements without requiring a multi-piece purchase.
Designed as an OEM-style replacement floor register for residential and light commercial forced-air HVAC duct systems.
Installation is typically performed by an HVAC technician or qualified installer. Shut down the HVAC system at the thermostat before removing an existing register to avoid debris entering the duct. Ensure the floor duct boot opening matches the register dimensions before securing the unit in place. Follow applicable local mechanical codes when selecting register placement and sizing.
