SteelCrest BTU18X6RWHH Fixed Return Grille 18x6

Product Description

The SteelCrest BTU18X6RWHH is a fixed return air grille engineered for wall and ceiling installations in residential and light commercial HVAC systems. Constructed from solid steel with a white powder-coat finish, it delivers a clean, slotted appearance alongside long-term corrosion resistance. The grille fits an 18 x 6 inch duct opening and installs with an overall face size of 20 x 8 inches, providing a finished look that covers rough duct edges. Licensed HVAC technicians and experienced installers use this grille as a direct replacement during system upgrades, new construction, and remodel work.

This grille is suited for return air applications in ducted forced-air systems. The fixed-blade slotted design maintains consistent airflow direction without adjustment, making it appropriate for low-profile return drops in walls or flush ceiling installations. The 18 x 6 inch duct size is a standard residential return dimension commonly found in single-family homes and light commercial spaces. Its finished face dimensions of 20 x 8 inches allow it to overlap standard drywall or plaster openings cleanly without additional trim work.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified tradesperson.
