The AquaStar 12 inch by 12 inch square Retro Wave main drain grate in white is designed for compatible drain applications where the grate itself needs to be replaced while preserving the surrounding installation. Replacement grates are useful because they let you refresh the visible and functional top portion of the drain without always replacing the full assembly.This part is especially useful when the original grate is cracked, discolored, worn, or no longer suitable for continued service. The white finish also helps maintain a clean and consistent appearance in the pool finish area.It is a practical service option when the drain assembly beneath remains usable but the top grate has reached the point where replacement is the better solution.
