The 2 in. x 12 in. Arch Louvered Design Cast Aluminum Floor Register is an elegant addition to any home decor. The brushed nickel finish has a lacquered coating for added protection. The damper box is made from a high impact plastic, not metal which can rust and seize up. This is not a cheaper option, it's the best option. The register fits a 2 in. x 12 in. opening. Color: Brushed Aluminum.
