The Tesla Undercover is designed to cover up the small access port on the bottom panel of the Tesla Model 3 When the hitch adapter is removed, the Undercover maintains factory designed aerodynamics and keeps any kind of debris or water from coming into the port when the receiver is not installed.
*If you have a 2019 Tesla Model 3, before ordering The Undercover, please inspect your vehicle. Some models are coming from the factory with a cover pre-installed
