Hart Cooley 657 10x6 Baseboard Return Air Grille White

Product Description

The HART COOLEY 657 10x6 is a baseboard return air grille designed for residential and light commercial HVAC duct systems. Built from one-piece steel construction, it features fins spaced at 1/3 inch intervals and set at a 20-degree angle, providing an exceptional free area for unrestricted airflow. A 7/8-inch margin turnback gives the grille a clean, finished look against the baseboard. The bright white enamel finish blends with standard interior trim. Licensed HVAC technicians and skilled installers handle this grille as part of a complete forced-air return system. The wall opening size is 10 inches wide by 6 inches tall, with an overall face size of 11-3/4 inches by 7-3/4 inches.

The 657 10x6 is intended for baseboard-level return air applications in forced-air HVAC systems. It serves as the complementary return air grille for HART COOLEY Model 654 and Model 664 supply grilles, allowing a matched appearance throughout a space. Fins can be installed facing upward or downward to best conceal the duct opening based on the specific installation layout. This grille is well-suited for residential construction and retrofit applications where baseboard returns are part of the duct design.
