Inspired by 19th-century Beaux-Arts design, our Carnegie Return-Air Grille with Pewter Finish is an authentic reproduction, just like those used in many of the Carnegie libraries throughout the United States. Originally cast in bronze, this modern update is made of durable, high-quality urethane resin that is both light weight and heat resistant. Whether used indoors or out, it will not rust, rot or corrode. It is suitable as a supply vent cover, decorative grilles, speaker grille, foundation vent or radiator cover. Hand cast and finished in the USA. For use on ceilings and walls only, do not install on floors. Pattern varies by grille size, see specs PDF below.
Dimensions: Boot size: the inside vented area of the grille. Grille size: 2" greater than the Boot size. Tensile Strength:7,660 psi. Flexural Strength: 10,230 psi. Heat Deflection: 212 degrees F. Fasteners: 1 5/8" drywall screws w/ color matched cover tabs.
Return Air Grilles are specifically designed for wall and ceiling installation, and should not be used as floor grilles. Learn about hardware >
