American Metal Products 375W12X6 Base Return Grille

Product Description

The AMERICAN METAL PRODUCTS 375W12X6 is a white baseboard return grille designed for low-wall return air applications in residential and light commercial HVAC systems. Constructed from painted stamped steel, it provides a durable, clean-finished cover for baseboard return openings measuring 12 inches by 6 inches. The grille features 1/3-inch fin spacing, which balances airflow with a consistent visual appearance. A 7/8-inch baseboard extension allows the grille to sit flush against standard baseboard trim without requiring additional adapters. Mounting hardware is included. This type of grille is typically installed by HVAC technicians or general contractors during new construction or system retrofits.

The 375W12X6 is suited for residential baseboard return air applications where a low-profile, wall-level return is needed. The white painted finish blends with standard interior trim. This grille is sold in a package of 10 units, making it practical for multi-room installations, new construction projects, or service contractors who stock common grille sizes. The stamped steel construction holds up to routine handling and normal residential HVAC service conditions.

Installation Notes

Baseboard return grilles are installed by HVAC technicians or general contractors as part of the duct termination at the wall. Power down the HVAC system before working near the return air opening. Secure the grille using the included screws, ensuring the fin direction aligns with the intended airflow path. Verify the rough opening dimensions match the grille size before installation to avoid gaps that reduce system efficiency.
