Disclosed is a swivel jack that comprises a central element with a wheel assembly to allow the jack to be transported when installed to a trailer. The central element is made up from multiple columns that are telescopically connected to one another to allow the jack to be raised and lowered. The central element is centrally positioned on a plate which rests on a base. Housed between the plate and the base are ball bearings which give rise to the swivel function of the swivel jack. The swivel jack comes equipped with a brake lock level that when depressed stops the wheel on the jack from rotating preventing movement of the trailer jack.
