All raised floor cutouts that allow communications cable to pass through in the hot aisle/cold aisle environment of a data center shall be equipped with a grommet to minimize bypass airflow. This grommet shall provide sealing properties for multiple cable bundles placed anywhere within the cable cutout. The grommet shall be designed to allow for retrofit applications to allow compatibility with vertical cable managers and cabinets. A low profile design is required that shall not have rigid features higher than 0.710 inches above the raised floor surface. The inside edge of the hole in the raised floor shall be covered to protect cables from abrasion as they pass through the raised floor.
