Abstract: A protective apparatus for a trailer tongue jack having a head and a column may include a protective cover having a shape that substantially conforms to the shape of the head, and an opening to accommodate the column when the protective cover is placed on the jack. First and second hook holders may be adapted to connect hooks for first and second trailer safety chains to the protective cover when the chains are not in use. A plug holder may be adapted to hold a plug for a trailer wiring harness when the harness is not in use. The protective cover may include an access port that aligns with a user interface on the jack when the protective cover is placed on the jack.
