The SteelCrest BSL30X20RWHH is a fixed-blade return air grille designed for wall and ceiling installations in residential and light commercial HVAC systems. Constructed from solid steel with a white powder-coat finish, it features a slotted decorative face that supports consistent return airflow back to the air handler or furnace. The grille fits a 30 x 20 inch duct opening and installs to an overall finished face size of 32 x 22 inches, covering the rough opening cleanly without additional trim work. HVAC technicians and contractors install this grille as a direct replacement or new-construction rough-in component.
This grille is suited for residential new construction, remodel projects, and direct-replacement applications on existing return air duct systems. The fixed-blade slotted design is appropriate for high-wall, sidewall, and ceiling return air locations where adjustable airflow direction is not required. The white powder-coat finish coordinates with standard interior trim and drywall finishes, making it a practical choice for finished living spaces.
Designed as an OEM-style direct replacement for fixed return air grilles serving standard 30 x 20 inch residential or light commercial duct openings on wall or ceiling surfaces.
Installation is typically performed by a licensed HVAC technician or qualified contractor. Shut down the air handling system before removing an existing grille or securing the new grille to the duct collar. Fasten to the wall or ceiling surface through the grille face or mounting flange using fasteners appropriate for the substrate. Verify the duct opening is clear of obstructions and that the 30 x 20 inch rough opening is sized correctly before securing the grille.
