It's a cap. It has 3 tabs underneath that slip into a round metal piece with cutouts for the tabs. Put the cap on, slip the round piece through the tabs, and bend the tabs to hold in place. Not a complete 100% seal but will keep water out as it's bigger than the hole and the hole has a lip. Allows for air flow and potentially insects but it's outside and the door to the while water heater cover has air vents in it anyway.
