ABSTRACT:
A receiver cover includes a stationary member that is configured to be secured to an end of a receiver of a trailer hitch. The receiver cover also includes a door which is hingedly connected to the stationary member. A biasing element, such as a spring, causes the door of the receiver cover to be biased in a closed position over the stationary element of the receiver cover. Thus, when the receiver is not in use, the door automatically closes and is secured in a closed position over a receptacle in a receiver with which the receiver cover is used. When access to the receptacle of the receiver is desired, such as for coupling a trailer hitch therewith, the door may be manually opened against the bias of the biasing element so as to expose the receptacle.
