Economical, lightweight aluminum grating sections are easy to handle, and hold up well in numerous installations. As one of our most economical products, Kadee’s aluminum grating only requires occasional mopping and can be lifted to remove dirt that has collected beneath the non-clogging tread bars, making this product virtually maintenance-free. Designed for level bed or pit applications. KADALi’s self-cleaning build limits tracked-in dirt or mud. With 50% free airflow levels, KADALi is ideal for air registers, and its all metal tread bar design eliminates carpet maintenance. Custom designs are available to fit almost any application.
